FKM Gum Copolymer
Order Quantity:
 
FKM Gum Copolymer

1. A-25, A-35 and A-45 are low Mooney Viscosity FKM gum with excellent fluidity, suitable to produce hose and sealing materials etc.

2. A-55, A-65 and A-75 are middle Mooney Viscosity FKM gum with excellent heat resistance, good fluidity , improved processing and metal bonding performance.

3. A-115 and A-125 are high Mooney FKM gum with excellent tensile strength, low compression set, improved mold release and metal bonding performance.

Package,storage and transportation:

1.Fluorotech FKM Gum is packed in PE bags in the form of flake, and then packed into carton with net weight 20kg per carton.

2.Fluorotech FKM Gum should be stored 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 as water during transportation.

3.It is suggested that Fluorotech FKM Gum storage 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.
