Perfluoroelastomers FFKM seal for Semiconductor Manufacturing
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers. High reliability for dynamic and static applications, as well as stability for corrosive media. Due to the bonding between carbon and fluorine atoms, FFKM currently offers the highest operating temperature range, the widest chemical compatibility, and the lowest levels of degassing and extractability.
KALFLUO® 9530 has excellent resistance to chemical corrosion, organic acid, inorganic acid, alkali, ester, ether, ketone, aldehyde, etc. It is applicable to the food and medical industry, especially in the processing of some plasma and gas deposition in the semiconductor manufacturing process. It has extremely low weight loss in oxygen and fluorine-containing plasma, and the maximum service temperature is 270 °C.
In semiconductor applications, FFKM O-rings help prevent pollution while providing chemical resistance and thermal stability. Due to their anti expansion and anti brittleness properties, FFKM O-rings can also be utilized in chemical process applications.

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.
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.
DKBI wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.
ID Face Seal for Cameron Type FLS Gate Valves, are spring-loaded, pressure-energized lip seal that improve gate and seat service life for all Cameron style FLS gate valves.
The PTFE gate valve seat seal is made of durable teflon, it is compatible with the Cameron gate valve type FC, FLS, and used in rotating equipment to minimize o-ring movement.
