Process safety instructions
- PVDF has good fire resistance and smoke inhibition property, however, when meets with fire, it will release toxic hydrogen fluoride gas and fluorocarbon compounds;
- Operators should take good care of personal protection during production.
Packaging and storage
- 25 kg and 250 kg packages can be provided. PVDF is packed in double layer of polyethylene plastic bag and then put into a hard cardboard drum.
- It must be stored in clean, cool, dry place.
