Optimal Pipes, Tubes and Hoses
Solef® PVDF qualities of impermeability and chemical resistance recommend its use in automotive fuel transport systems. A layer of Solef® PVDF within the construction of a multi-layer fuel line enhances the strength, permeation resistance and durability of the hose.
Industries such as Chemical Processing rely on Solef® PVDF to withstand heat and pressure, aggressive chemicals, mechanical stress, and abrasive particles in varied applications:
- Chemical production
- Transport and storage systems
- Filtration and separation equipment (filters, membranes, housings)
- Heat exchangers
Gas Sampling Bags
Gas sampling bags fabricated from Ajedium Solef® PVDF film are inert to most gases and resist gas permeation.
Films are available from 1 mil up to 55” wide and are designed to retain their properties when exposed to a variety of chemicals over a wide range of temperatures. Moreover Solef® PVDF does not contain additives that could eventually leach out during service and will not demonstrate particle generation over time.
Solef® PVDF films are readily thermo weldable. Tensile tests performed on the welded seams have proven that fusions are as 100% reliable as the original material.
Pumps and Filters Diaphragms in Chemical Industry
Thanks to its chemical resistance and high service temperature, Solef® PVDF films are used in the manufacturing of diaphragms for pumps and filters used in CPI applications.
Photovoltaic Backsheet Films
Solef® PVDF films are ideally suited as a component in backsheet laminates used in photovoltaic modules. PVDF offers an excellent combination of properties from UV stability to water vapor permeation resistance making it an excellent choice. Solef® PVDF can be laminated to PET to provide the traditional fluoropolymer-PET-fluoropolymer or fluoropolymer-PET structure currently available in the marketplace.
Antigraffiti Covering Films
Thanks to their chemical resistance and low surface tension, Solef® PVDF films are used to protect surfaces from graffiti. PVDF high chemical resistance allow the use of aggressive cleaning agents to remove inks and its low surface tension reduces the adhesion of graffiti.
Wind Power Protective Films
Solvay offers protective films made by Solef® PVDF which offer high resistance to environmental conditions and lower friction for wind mills blades and turbine generators.
- Abrasion resistance
- Low coefficient of friction
- Unaffected by UV (>232 nm)
- Good adhesion of various substrates with specific grades
Solef® PVDF is a chemically resistant polymer with high thermal stability for the fuel cell system's balance of plant components such as manifolds, fuel tubing, fittings, valves, recipients, etc.
Thanks to its stable and reliable performance, Solef® PVDF is one of the preferred choice as binder material for electrodes. Furthermore, Solef® PVDF can be used for producing battery separators offering various advantages in the design of the separator, used as main component or even just as a thin coating layer.
Solef® PVDF possess all the characteristics necessary to make hollow fiber, flat sheet and tubular membranes with the pore size and separation selectivity needed in the realization of bioprocessing and medical filtration membranes and food and beverage processing membranes.
Solef® PVDF has been used in the harsh environments of down-hole and sub-sea oil production for many years due to its proven thermal, chemical resistance and barrier properties.
Solef® PVDF has been used since the 1990's as pressure sheath in flexible risers, unbonded multilayer metal/polymer pipes which convey crude oil from subsea wells up to fixed platforms or floating installations.
Solef® 90615/2002 for Steel Pipe Liners
Solvay continues to innovate in oil and gas with it’s new PVDF grade, Solef 90615/2002, designed especially for the demanding application of steel pipe polymer liners for onshore and offshore. With it’s combination of high ductility, high thermal rating to 150C and exceptional resistance to oil fluids, it can also be applied to the application of high temperature or high pressure flexible pipes for offshore, and any other application where a flexible PVDF needs to meet these kinds of rigorous conditions.
