• Process safety instructions

1. This product should be processed under 260ºC to avoid producing toxic gases.
2. PVDF has good fire resistance and smoke inhibition property. However, it releases toxic xxxxxx 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 PE plastic bag and then packed in cardboard box with the net weight 20KGS. It must be stored in clean, cool, dry place.
