KR370 (Bisphenol /Diamine Cureable Terpolymers Raw Gums)

FKM (Fluorocarbon Rubber or Fluoroelastomer) Raw material


Technical Information
FLUONOX®KR370 is a high viscosity terpolymer consisting of VDF, HFP and TFE with 68% Fluorine content. It does not contain curatives; It can be cured with diamine orbisphenol AF curing systems.

FLUONOX®KR370 is suitable for applications which need improved chemical resistance and long-term heat resistance compared to fluoroelastomer copolymer. This grade is designed for compression molding of shaft seals, valve stem seals, O-rings, bonded seals and gaskets.

Product features
* Good compression set
* Outstanding mould release
* No mould fouling

Safety and Handling
Handling and processing of fluoroelastomer must be done in ventilated areas to prevent personnel exposure to the fumes liberated during curing or use of cured rubber at high temperature. During the process, some fumes may generate at high temperature which are harmful for human beings. Fumes should not be inhaled; eye and skin contact must be avoided. In case of skin contact flush skin with cold water immediately. In case of eye contact, flush with water immediately and seek medical help. Smoking tobacco or cigarettes should not be allowed in working area. Mixing agents that contain metallic particulate such as powdered aluminium can rapidly decompose at high temperature; therefore do not use metallic particulate as mixing agent. Fluoroelastomer should be stored away from heat. It should be kept in clean and dry area where it can be protected until it is used. Please read the Material Safety Data Sheet before handling the product.
