What is Vinylidene fluoride?
Vinylidene fluoride (CAS 75-38-7), also known as Halocarbon 1132A, is a gaseous fluorinated monomer; the primary building block in producing high-performance fluoropolymers.
Where is Vinylidene fluoride used?
- Plastics and polymers: polymerized into PVDF resin for pipes, films, coatings and membranes in chemical processing and semiconductors
- Copolymers with hexafluoropropylene give fluoroelastomers such as FKM and Viton-type compounds for seals, gaskets and O-rings in automotive and aerospace assemblies
- Batteries: PVDF binder in lithium-ion electrode fabrication
- Rubber and specialty compounding: fluoroelastomer compounds for fuel system components and high-temperature hoses
- It is the key feedstock for polyvinylidene fluoride and fluoroelastomers needing chemical resistance, thermal stability and durability.
Commercial specifications
- Polymerization-grade purity
- Specifications controlled for inhibitor content
- Moisture levels strictly monitored
