Acrylic Rubber Properties

The chemical name of this rubber is alkyl acrylate copolymer.

Acrylic rubber properties.

The key properties of polyacrylic acm are its resistance to hot hydraulic oil and oxidation. Vamac ethylene acrylic elastomer is used across the globe for automotive powertrains and other applications that require heat and chemical resistance as well as those that demand specific rubber like qualities. Polyacrylic elastomers also called acm rubbers are synthetic rubbers composed of acrylic monomers. It is generally resistant to ozone extreme pressure lubricants hot oils petroleum solvents animal and vegetable fats.

The outstanding property of this rubber is its resistance to hot oil and to oxidation. Acrylic rubber is a type of synthetic rubber containing acrylonitrile. These polymers are usually prepared by emulsion or suspension polymerization. These properties especially the low oil swell allow rubber part makers better lifetime expectations.

Acm is polar and doesn t contain unsaturation. Acrylic rubber known by the chemical name alkyl acrylate copolymer acm or the tradename hytemp is a type of rubber that has outstanding resistance to hot oil and oxidation it belongs to specialty rubbers it has a continuous working temperature of 150 c 302 f and an intermittent limit of 180 c 356 f. Vamac also helps provide longevity in powertrain applications and air management systems and delivers long term durability in other environments with diverse chemical exposure. Low temperature applications are limited to 10 c.

Unlike butadiene based rubbers sbs nbr acrylic elastomers have good resistance to mineral oils oxygen ozone ultraviolet radiation and withstand higher temperatures. The main repeat units are ethyl and butyl acrylate or a blend of both. Aem is resistant to heat chemicals ozone and oil and offers good resistance to lubricating oils and greases even those containing aggressive additives and to power steering and transmission fluids. It is also resistant to ozone and weathering and in these respects it is much superior to nitrile rubber.

Acm polyacrylic rubber. Acrylic rubber acm is a specialty synthetic rubber used when resistance to petroleum fuel oil oxygen ozone and heat are required. Both have similar mechanical properties however aem s can withand a wider temperature range than acm s and hydrogenated nitriles hnbr. Acm polyacrylic rubber properties.

Acrylic rubber acm noxtite pa. Water resistance is poor as is its resistance to acids and alkalis.
