Peroxide system FKM raw material  High Fluoride content



1: Additive of high Mooney rubber, O-ring, anti-extrution parts of product

2: O-ring made by compression moulding, injection moulding and imjestion, extruded hose

3: Calendaring sheet, skeldtal oil seal, extruded hose, etc.

4: General parts made by injection moulding, and oil seals, etc.

5: Parts made by compression mouldiong, high strength vulcanized products.


Main Applications

Widely used in high temerature, aviation, automobile, petroleum and chemical imdustries, oils lubricants, etc. Mainly used to produce gaskets, O-rings, V-rings, sealing bowl with metal bone, diaphragms, tube, valve-plate, rolls, etc.


1,Fluoroelastomer gum has good thermal stability below 260℃; It will minimally decompose when placed in the temperature of 260℃-300℃ for a long time; When hither than 320℃, it will quickly decompose, and poisomous HF and fluorocarbon organic compound are produced; When it meets fire, it also release poisonous HF and fluorocarbon organic compound.

2, FKM shouldn' t be calandered with metal powder (such as AI and Mg) or animine compound more than 10%. If that happpens, emperature will arise and several element will react with FKM, which will damage the equipment and operators.
