Kalrez® Parts Chemical Resistance
Kalrez® perfluoroelastomer (FFKM) parts withstand attack from more than 1,800 chemicals, solvents and plasmas. The Kalrez® product line delivers outstanding performance in aggressive process environments. Whether it’s resistance to acids, amines, plasma, ultrapure de-ionized water or strong bases, by selecting the Kalrez® product that is best suited to a specific application, manufacturers can improve seal performance in their operating environment. Kalrez® parts are available in a number of different compounds that are formulated to optimize properties and give the best possible performance in various chemicals and temperatures. The Kalrez® Application Guide can help users select the preferred product for temperature and chemical resistance.
Minimal Swell
Chemically induced swelling can cause O-rings and sealing components made of other elastomers to extrude out of seal grooves, resulting in seal failures. Kalrez® parts resist extreme volume swell when exposed to a wide variety of chemicals and solvents, including concentrated nitric acid, sodium hydroxide, ethylene diamine and steam. They have proven to be a cost-effective solution in sealing situations that require the greatest resistance to harsh chemical environments and high temperatures.
Powered by a broad product portfolio and state-of-the-art expertise, we help our partners meet the critical industry demands of the electrical and electronics market.
