Process safety instructions

PVDF has good burning suppression performance and smoke suppression performance, 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.
