  • Process safety instructions
  • This product should be processed under 260℃ to avoid producing toxic gases.
  • PVDF has good fire resistance and smoke inhibition property. While, it will release toxic hydrogen fluoride gas and fluorocarbon compounds when meets with fire.
  • Operators should pay attention to personal protection during the processing and operating.
  • Packaging and storage

PVDF is packed in PE plastic bag and then be put into a drum with the net weight 25KGS. It must be stored in clean, cool, dry place.
