Process safety instructions
1)This product should be processed under 260℃ to avoid producing toxic gases.
2)PVDF has good fire resistance and smoke inhibition property. While, it will release toxic hydrogen fluoride gas and fluorocarbon compounds when meets with fire.
3)Operators should pay attention to personal protection during the processing and operating.
Packaging and storage
PVDF is packed in a plastic bag and then be put into a PE bag with the net weight 25KGS. It must be stored in clean, cool, dry place.
