MCS 352 Resistant O-Rings and Seals
MCS 352, also known as methyl chlorosilane, is a colorless and flammable gas with a strong odor. Common uses include as a chemical intermediate in the production of silicone-based products, and as a cleaning agent in the production of semiconductors and glasses.
When rubber is exposed to MCS 352, certain rubber types are prone to rapid degradation due to the chemical’s corrosive nature. O-rings, gaskets, and other seals made of natural rubber, neoprene, and other rubber materials can be damaged quickly when exposed to this chemical. This can lead to seal failure, leakage, and other issues. Additionally, rubber materials may be subject to swelling, cracking, and discoloration when exposed to this chemical.
EPDM (EP, EPR, Ethylene-Propylene Rubber)
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals. Marco Rubber has the world’s largest inventory network of EPDM o-rings and made on demand custom manufacturing often without tooling fees, so the EPDM o-rings you need are always available. Whether it’s for water systems, braking systems, medical, pharmaceutical, food or dairy use, you can count on Marco Rubber to deliver your o-rings fast and efficiently.
