FKM Gum Terpolymer

Catalog Number

ACMA00045154

Description

FKM terpolymer is copolymer of vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene. Because of its high fluorine content, its vulcanized rubber has excellent oil resistance and high thermal stability, it also has good mechanical property, can be used in 2750C for long time. FKM terpolymer is widely used in aerospace, automotive, machinery, petrochemical, and other fields.

Storage

1. FKM Gum is packed in PE bags in the form of flake, and then packed into carton with net weight 20kg per carton.
2. 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.
