Monomethyl hydrazine is also known as methylhydrazine, methyl hydrazine, monomethylhydrazine, and hydrazinomethane. It is commonly used as a rocket fuel and is used in the production of fertilizers and other agricultural chemicals.
When rubber is exposed to methylhydrazine, it can cause premature failure of the rubber due to the solvent power of the chemical. Rubber is particularly prone to swelling, hardening, softening and cracking when exposed to this chemical. In extreme cases, the rubber may become brittle and crack leading to possible leakage of the sealed material.
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.
