Dow Chemical ET588 is also known as polyglycol-based polyurethane (PGU) and is a synthetic rubber that is used in a variety of applications such as industrial rollers, rollers, and conveyer belts. Common uses for PGU include rollers, conveyer belts, and industrial rollers.
PGU rubber may be susceptible to failure when exposed to certain chemicals, such as hydrocarbons, ozone, and acids. Hydrocarbons can cause hardening, cracking, and embrittlement of the rubber. Ozone can cause hardening and embrittlement, while acids can cause swelling, softening, and discoloration of the rubber, leading to premature failure.
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.
