Package、storage and transportation:

(1). Fluoroelastomer is packed in PE bagsin the form of flake, and then packed into carton with net weight 25kg per carton.

(2). Fluoroelastomer should be stored in clean, dry and coolwarehouse. It can be transported as non-hazardous chemicals and should be far away from pollution sources, sunshine as well as water during transportation.

(3). It issuggested that Flurine fluoroelastomer storing time limit should be one yearafter production. If exceeding one year, these products should be retested,they could be used continuously after being retested up to grade.
