2.  The basic formula:

     FKM raw gum: 100g;

     Bisphenol AF: 2g;

     Vulcanization accelerator BPP: 0.5g;

     MgO: 3g

     N990 MT Carbon Black: 30g

     Ca(OH)2: 6g;


3.  Package, storage and transportation:

(1). Fluoroelastomer is packed in PE bags in the form of flake, and then packed into carton with net weight 20kg per carton.

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

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