FFKM O-Ring Sealing Solutions for semiconductor applications


FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials. FFKM O-rings can be used in the most demanding applications, with dozens of compounds specifically designed to achieve target application performance such as low or high temperature, chemical compatibility, and industry compliance.


KALFLUO® 8520 has excellent resistance to chemical corrosion, organic acid, inorganic acid, alkali, ester, ether, ketone, aldehyde, etc. It has outstanding heat-resistant air aging performance. It can be used in the environment of high temperature hot air in the semiconductor manufacturing process, and the maximum operating temperature is 315 °C. It can be made into o-ring, diaphragm, gasket, rubber strip, rubber plate and customized products.


To support the replacement and upgrade of seals in semiconductor industry and medical equipment industry, JST has devoted to R&D on semiconductor FFKM compounds, medical & food compounds, and set up a class 10,000 clean room.


We have more optimized and advanced production processes, a higher-standard quality control system, a more accurate logistics control system, as well as a safer, healthier and more environment-friendly management system.
