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, 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.


Packaging andstorage

PVDF is packed in PE plasticbag contained in a 25Kg or 50Kg drum. It must be stored in clean, cool, dry place.
