BLEACHING LYE Resistant O-Rings and Seals
Bleaching lye, also known as sodium hydroxide or caustic soda, is a strong alkaline solution used for bleaching, cleaning, and various industrial processes. Common uses for this chemical include paper manufacturing, soap and detergent production, and food processing.
When rubber is exposed to bleaching lye, it can suffer from a number of different types of failures. The most common type of failure is swelling and softening of the rubber as a result of the alkaline environment. Additionally, bleaching lye can corrode and degrade rubber, leading to cracking and other mechanical failures. Other types of failures include discoloration of the rubber and embrittlement due to the high pH of the solution.
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.
