Perfluoroelastomer FFKM O rings and seals manufacturer in China
Perfluororelastomer FFKM Series
This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries. In addition to chemical inertness and thermal stability, FFKM also has the unique elasticity and durable sealing force of synthetic rubber. FFKM has excellent chemical corrosion resistance and high temperature resistance characteristics, which makes FFKM widely used in various harsh working conditions for chemical applications.
JST's FFKM compound is known as KALFLUO™.

FFKM O-ring is a circular seal made of perfluoroelastomer compound, with a higher fluorine content than FKM fluoroelastomer.
Many industries use FFKM O-rings in critical applications where sealing failure is strictly prohibited. These industries include chemical processing, energy, semiconductors, pharmaceuticals, oil and gas recovery, aerospace, and other industries.
FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
JST ESY series design is commonly used as dynamic seal for ball valve stem, and the ESY with various V rings and T shape support rings could be used for fugitive emission valves, meeting the requirements of ISO-15848.
The water pump seal D1 is composed of one or couple of fabric reinforced Chevron V rings (DM), back up ring (DD) and header ring (DS) for plunger sealing.
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material.
