1.PVDF should be processed under 260℃,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.


PVDF is packed in PE plastic bag and then be put into a drum with the net weight 20KGS. It must be stored in clean, cool, dry place.
