Process safety instructions
1. This product should be processed under 370℃,to avoid producing toxic gases;
2. PVDF has good fire resistance and smoke inhibition property, however, when meets with fire, it will release toxic hydrogen fluoride gas and fluorocarbon compounds;
3. Operators should take good care of personal protection during the use procedure and processing.
Packaging and storage
1. 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.
2. It must be stored in clean, cool, dry place.
