Update: Apr. 2006
1. Description:
- HFP is one of the important monomers of fluoropolymers. It could react with VdF
to make fluoroelastomer copolymer, with TFE and VdF to make fluoroelastomer terpolymer,
and with TFE to make FEP. All these fluorinated polymers are special chemicals necessary
for modern industries. HFP is the essential raw material of the new and pollutionless
extinguishing agent F227.
