Greener homes start with better foams

SOLKANE-Insulation

SOLKANE® products continue to be among the most reliable, safe, efficient and cost-effective options for today’s competitive business environment. 

SOLKANE® blowing agents are an important component in order to produce foams such as polyurethane (PU) foam, which provide best thermal insulation properties. Thermal insulation is part of the state-of-the art way of construction, be it for individual houses, commercial complexes, industrial structures or public buildings. In this area rigid polyurethane foams (PUR) are established as the most efficient thermal insulation material that is manufactured on industrial scale. This behaviour is used in Transport Cooling (Trucks/Reefers etc.) too.

Chlorinated hydro-fluorocarbons are currently being replaced by ecofriendly alternatives - in particular the state of the art foaming agent SOLKANE® 365/227.

SOLKANE® 365mfc, for example, is a hydrofluorocarbon of the latest generation. It has no ozone depleting potential and is a perfect team player. It is miscible with a wide range of other organic foam blowing agents like other HFCs or even hydrocarbons - the choices are almost unlimited. 

IXOL is a high performance halogenated polyether polyol, which acts as a reactive flame-retardants for polyurethanes and rigid polyurethane foams.

SOLKANE® 365 Foaming Agents

A foaming agent of the third generation without ozone depletion potential

SOLKANE® 365 is a hydrofluorocarbon of the latest generation. It has no ozone depleting potential and with its boiling point of 40 °C it can be handled as a true liquid at room temperature. It is a colorless, compound with a faintly ethereal odor, used for a wide range of applications within PU foams, solvents or heat transfer fluids.

The chemical stability of SOLKANE® 365 is even better when compared to HCFC 141b. Therefore no stabilizer is needed if SOLKANE® 365 is stored under appropriate conditions (for details please refer to our SDS).

SOLKANE® 365 is a perfect team player. It is miscible with a wide range of other organic foam blowing agents like other HFCs or even hydrocarbons.

The choices are up to you and almost unlimited. Blending of i.e. cyclopentane with SOLKANE® 365 strongly improves the lambda value while reducing the density of the resulting PU foam. That means, running SOLKANE® 365 in your system minimizes raw material costs while improving insulation performance. That is what we call a win win situation!

SOLKANE® 365 is your first choice when fire safety is demanded. Fire classifications and fire performance tests are of increased importance for modern PU products especially in the building industry. Combined with the Solvay's IXOL® range of reactive flame retardant polyols, SOLKANE® 365 blown PU foams reach the highest possible classifications for organic insulation materials.

SOLKANE® 365/227 Blends

Liquid hydrofluorocarbon blends of the third generation without ozone depletion potential

SOLKANE® 365 is the key component to form a range of promising blowing agent blends. For safety applications a non-flammable HFC-blend is of special interest. SOLKANE® 227ea is commercially produced propellant for pharmaceutical aerosols. Blends of SOLKANE® 365 and SOLKANE® 227ea have been checked for a flash point using an Abel Pensky closed cup flash point apparatus, in accordance to DIN 51 755-1.

A blend of SOLKANE® 365/227 with 5 pbw of SOLKANE® 227ea has no flash point and is classified as a non-flammable liquid. It has to be pointed out that this blend is non azeotropic, and the compound SOLKANE® 227ea evaporates first during handling. To have a safety margin Solvay therefore recommends the blend SOLKANE® 365/227 with 7 pbw of SOLKANE® 227ea. This blend starts boiling at ~30 °C and is developed for foam producers. For System Houses Solvay developed the blend SOLKANE® 365/227 87:13, as the used polyols have an influence to the flash point behaviour.

Although the blend SOLKANE® 365/227 has no flash point, it has flammability limits in air. Such a situation is well known with for instance SOLKANE® 141b or Methylene Chloride. 

SOLKANE® 141b

A high purity liquid that has a wide range of applications in the plastic foams sector.

Because of its low gas phase thermal conductivity SOLKANE® 141b was the best available replacement to CFC11 as a blowing agent for rigid polyurethane insulating foams. In the meantime it is part of phase-out-scenarios in many countries all over the world, but deliveries from Solvay are still possible into regions where the phase-out is not completed.

IXOL® B251

The fire fighter in your foam. Particularly well suited for the production of rigid polyurethane foams.

IXOL® B251 is also suitable for the development of formulations having high fire performance according to the European standard based on the Single Burning Item (SBI) test. As example, formulations containing the polyol IXOL® B251 can lead to the manufacture of sandwich panels with a class B according to the European classification. This is the highest level that can be achieved by polyurethane foams. 

The polyol IXOL® B251 affect the thermal insulation characteristics of the foam or its mechanical properties positively. It can be used in various concentrations in combination with standard polyether or polyester polyols. IXOL® B251 is also suitable for manufacturing of modified isocyanurate polyurethane foams (PUIR: also known as low index polyisocyanurate foams).

Applications

Thermal insulation is part of the state-of-the art way of construction, be it for individual houses, commercial complexes, industrial structures or public buildings. In this area rigid polyurethane foams (PUR) are established as the most efficient thermal insulation material that is manufactured on industrial scale. The outstanding characteristics of this cellular material are becoming nowadays a major item because of the necessity to protect our environment, in particular by reducing the emissions of greenhouse gases through a lower energy consumption (reduction of carbon dioxide emissions). 

For obvious safety reasons, rigid polyurethane foams must comply with various standardized tests defined by national or international regulations. IXOL® B251 gives the possibility to produce rigid polyurethane foams which can achieve the requirements of many European and American tests. Rigid polyurethane foams formulated with IXOL® B251 in particular can pass  tests even with high requirements. 

The polyol IXOL® B251 is compatible with all usual polyols and with non reactive flame retardants such as phosphoric acid esters. It presents moreover useful synergism with these compounds. 

The use of IXOL® B251 offers therefore considerable flexibility in formulation. Nevertheless, system houses are advised to check that their formulations do not alter with time whenever a long term stability of the polyol blend is required. 

Formulations containing the polyol IXOL® B251 can be used in the most varied processing techniques such as e.g.: 

  • Injection moulding in "sandwich" plates for the manufacture of cladding panels or elements for cooling chambers and cold stores 
  • Continuous production of panels (laminates)
  • Manufacture of block foams which can be cut into plates or tailor-made shapes 
  • In-situ projection or cast molding for roof tightening and insulation, vertical or under-face insulation. 

  
For one-component foams we also offer IXOL® M125, a diol with a lower hydroxyl number and a lower viscosity.  

IXOL® M125

Flame retardant for your canned foam. Particularly suited for one component polyurethane foams.

The polyol IXOL® M125 is a halogenated aliphatic polyether diol, particularly suited for one and two component polyurethane foams.

Due to its low functionality, IXOL® M125 is particularly suited for one component polyurethane (PUR) foams to meet high standards in fire safety. Being a reactive compound, IXOL® M125 polyol guarantees a permanent flame retardant effect since the halogens are chemically bound to the final polymer.

IXOL® M125 has been manufactured in our Tavaux plant (France) for about 30 years. As a mature product the manufacturing process is proven and runs totally under computer control, which ensures optimum and constant quality. Furthermore the plant is certified according to ISO 9002 standard.

Applications

The polyol IXOL® M125 is compatible with all usual polyols and with flame retardant additives such as for example phosphoric acid esters. IXOL® M125 has a good premix stability in preformulated systems, even if stored for a longer time. The use of IXOL® M125 therefore offers full flexibility in formulation. 

Nevertheless, formulators and users are advised to check that their formulations or the properties of their resulting foam do not alter with time, when long term stability of the blends is required. 

IXOL® M125 is a medium viscous polyol at room temperature which enables an easy processing or use in special application such as one component foams (OCF). 

Product uses

IXOL® M125 imparts advantages as a high performance flame retardant in the following main applications:

  • One component foams: IXOL® M125 used in combination with polyether polyols or with polyester polyols gives a foam achieving a high flame suppression standard, for example the B2/B1 classification in OCF. 
  • PIR foams blown with HCFCs such as Solkane 141b or hydrocarbons such as n-pentane: The use of IXOL® M125 allows a reduction of the isocyanate index and therefore has a positive impact on the foam friability. 
  • Adhesives: IXOL® M125 improves the fire performance of PU based adhesives. 
  • PU-based Glue systems can be improved by addition of IXOL M125 according the fire behaviour.

 

Solkane Specialties mainly serve applications and technologies that are only emerging today but that have potential to play a vital part in solving tomorrow’s energy problems of a growing population.

SOLKANE-Specialities

Organic Rankine Cycle (ORC) units are able to extract electricity from low temperature waste or geothermal heat. Solkatherm – available in several grades – has already proven its superior performance in this segment. Other applications include immersion cooling or (thermal) heat recovery applications. Our Solkaflam fire fighting agent completes the line of Solkane specialties.  

SOLKAFLAM® 227 UL

High grade electronic requires the highest standard of fire protection: an ideal deployment zone for SOLKAFLAM®

SOLKAFLAM® 227 UL is an important halon substitute primarily in occupied areas where space and/or weight are constrained, or speed of suppression is important. The range of these specialized fire protection applications include:

  • Creating fire protection, where high value equipment is involved and personal safety must be considered. In these situations, water or dry chemicals could damage or destroy equipment, whereas SOLKAFLAM® 227 can effectively suppress a fire without damaging the equipment and endangering personnel who might require a significant part of a minute to exit the area. Computer rooms and data centres are prototypical examples for this application.
  • Suppressing burning or explosion of flammable vapor in the air, for example; in aircraft jet engines or at gasoline service stations.
  • Fire protection in maritime areas such as ships, oil platforms and other maritime bases.

New Generation Fire Extinguishing Agents

Since the 1960's halons, and especially Halon 1301 (CBrF3) have been widely used as fire extinguishing agents and well known for its low toxicity and high efficiency, the latter being accounted to the bromine content.

Nevertheless, as bromine, like chlorine, is responsible for depleting the protective stratospheric ozone, the manufacture, sale and use of halons have been regulated under the terms of the Montreal Protocol.

While the production of halons has already been banned, the usage of halons in hand-held fire extinguishers and total flooding systems has been forbidden in the European Community since 2003 (EC Regulation2037/2000). Since the beginning of 2004 the use of halons is only permitted for critical applications with an exemption license and the refilling of halon containing systems is prohibited.

Accordingly, new systems based on nitrogen, argon and carbon dioxide were launched. These standard fire extinguishers operating with powder, water or carbon dioxide are becoming increasingly more used, plus, for special applications, the new generation hydrofluorocarbon  fire extinguishing agents HFC 125 (pentafluoroethane) and HFC 227 (heptafluoropropane) were launched. Specifically, replacements for Halon 1301, requiring comparable extinguishing concentrations, exhibiting similar suitable toxicity profiles at used concentrations, and providing universal handling possibilities.

SOLKATHERM® SES36

A high temperature working fluid

SOLKATHERM® SES36 is an azeotropic mixture of SOLKANE® 365mfc which boils at 36.7°C. This means that its handling is particularly easy because: 

Azeotropic mixtures behave like a single-substance. The liquid and vapor phase have the same composition; transferring, evaporating or condensing SOLKATHERM® SES36 will not affect its composition. 
Substances which can be transported as liquid have, by definition, at 50°C a vapor pressure lower than 3 bar. They can be filled into containers which are not pressurized gas cylinders. These containers have to comply with minimal burst pressure requirements and they are easy to handle. 

SOLKATHERM® SES36 has a wide compatibility range with many common materials. It is generally compatible with all non-fluorinated plastics and rubbers, if we exclude as notable exceptions PMMA and natural rubber.

Main characteristics

  • It is a non flammable liquid, but its vapors form flammable mixtures with air in the range 3,9% (LFL) – 11,7% (UFL). The Minimum Ignition Energy (MIE) of SOLKATHERM® is very high: 130mJ. For comparison, we report hereafter the MIE of other reference materials: methane 0,4mJ; R152a 0,35mJ; n-pentane 0,22mJ. Only strong electric discharges and naked flames have the energy to ignite SOLKATHERM® vapors. 
  • The flame does not propagate to the liquid phase. 
  • It is not listed as toxic substance; it does not represent a health hazard if used properly. 
  • It has a characteristic odor of 'solvent'. It can be detected by smell before it reaches large concentrations in air. Its vapors are heavier than air and have the tendency to disperse at ground level. 
  • It is colorless, it looks like water. It boils fast and at a relatively low temperature subtracting heat from the environment. In this, its behaviour is similar to many other well-known solvents like alcohols or ethers. 
  • It is chemically stable. It is compatible with most construction materials. 
  • It is thermally very stable. Its first decomposition reactions occur in laboratory at 220°C. It has been proved in continuous operation conditions up to 190°C. 
  • Auto-ignition is at 580°C

Applications

  • Direct Contact Cooling
  • Heat Pipes
  • ORC-cycles
  • Heat transfer fluid
  • High temperature Heat Pumps

SOLKATHERM® SES24 is a zeotropic mixture with a NBP of 21.4°C and a temperature glide of 15.7 K. SOLKATHERM® SES24 is especially designed for high temperature application e.g. ORC and heat pumps using single phase heat sources and heat sinks.

Applications

  • Direct contact cooling
  • Heat pipes
  • ORC-cycles
  • Heat transfer fluid
  • High temperature heat pumps

Material Compatibility

SOLKATHERM® SES24 has a wide compatibility range with many common materials. It is generally compatible with all non-fluorinated plastics and rubbers, if we exclude as notable exceptions PMMA and natural rubber.

Due to the relative chemical similarity, the compatibility of SOLKATHERM® SES24 with fluorinated plastics and rubbers is not as wide as it could be expected from the superior chemical resistance that normally those materials are able to assure. As an example, some fluorinated rubbers o-rings (Viton® types) are not suitable in systems filled with SOLKATHERM® SES24. As a positive exception, PTFE has proven to be compatible.

As an example, some fluorinated rubbers o-rings (Viton® types) are not suitable in systems filled with SOLKATHERM® SES30. As a positive exception, PTFE has proven to be compatible.

Construction Industry - Thermal Insulation

SOLKANE® blowing agents are an important component in order to produce foams such as polyurethane (PU) foam and extruded polystyrene, which provide thermal insulation

SOLKANE® 365mfc is a hydrofluorocarbon (HFC) of the latest generation. It has no ozone depleting potential and is used for a wide range of applications within PU foams, solvents or heat transfer fluids.

SOLKANE® 365/227 are binary blends of SOLKANE® 365mfc and SOLKANE® 227ea. This blend is the best choice to replace the ozone depleting hydrochlorofluorocarbon (HCFC) 141b. The blends are designed for rigid PU foams for insulation purposes, where a non flammable liquid foaming agent with a low thermal conductivity and a high performance foam expansion is needed. With SOLKANE® 365/227 it becomes possible to cover a wide range of temperature insulation. Foams produced with the HFC blend of SOLKANE® 365/227 have a fine cell structure with good insulation properties and have the best compressive strength when compared to other possible hydrocarbon pentane co-blends.
