UNSYMMETRICAL DIMETHYL HYDRAZINE is also known as UDMH, hydrazine hydrate, N2H4(L), and hydrazine. This chemical is commonly used in rocket fuels, agricultural chemicals, and as an intermediate in the manufacture of other chemicals.
When exposed to this chemical, rubber materials tend to become brittle and crack due to the chemical's strong oxidizing properties. This can lead to leaks and other failures in the rubber materials. Rubber materials that are exposed to UDMH for an extended period of time are also prone to swelling, hardening, and dry rotting.
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.
