Acrylic Rubber

Acrylic Rubber, ACM, is a specialty synthetic rubber used when resistance to petroleum fuel, oil, oxygen, ozone and heat are required. It is generally resistant to ozone, extreme pressure, lubricants, hot oils, petroleum solvents, animal and vegetable fats. It is generally attacked by water alcohols, glycols, alkali, esters, aromatic hydrocarbons, halogenated hydrocarbons and phenol. This synthetic rubber is used extensively in the automotive industry for transmission applications, bearing seals, o-rings and gaskets.
