Polyvinylidene fluoride resin manufacturer
PVDF polyvinylidene fluoride
This product should be processed at temperatures below 370 °C to avoid the generation of toxic gases;
PVDF has excellent flame retardant and smoke suppressing properties, but when exposed to an open flame, it still releases toxic hydrogen fluoride gas and fluorocarbon organic compounds;
Operators should be personally protected during use and processing.
