1,1-Dichloro-2,2,2-trifluoroethane

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.

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 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.
