ALUM POTASH Resistant O-Rings and Seals
Alpha Picoline is also known as methyl amine, methyl ethyl amine, and dimethyl amine. It is commonly used as a solvent, a metal cleaning agent, and a reaction intermediate in the chemical industry. In the rubber industry, alpha picoline is used as a plasticizer to improve the processability and reduce the viscosity of rubber compounds.
When rubber is exposed to alpha picoline, it can cause swelling and a breakdown of the rubber due to the plasticizing effect of the chemical. This can cause the rubber to become brittle and eventually lead to cracking, tearing, and eventual failure of the rubber seal. Additionally, the rubber can become discolored due to the reaction of the alpha picoline with the rubber.
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.
