It is generally resistant to ozone extreme pressure lubricants hot oils petroleum solvents animal and vegetable fats.
Acrylic rubber properties.
The chemical name of this rubber is alkyl acrylate copolymer.
Low temperature applications are limited to 10 c.
Acm is polar and doesn t contain unsaturation.
Acrylic rubber is a type of synthetic rubber containing acrylonitrile.
These polymers are usually prepared by emulsion or suspension polymerization.
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.
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.
The outstanding property of this rubber is its resistance to hot oil and to oxidation.
Acm polyacrylic rubber properties.
The main repeat units are ethyl and butyl acrylate or a blend of both.
Today s engine and transmission requirements would be difficult to meet cost effectively without acm.
Vamac also helps provide longevity in powertrain applications and air management systems and delivers long term durability in other environments with diverse chemical exposure.
The key properties of polyacrylic acm are its resistance to hot hydraulic oil and oxidation.
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.
Both have similar mechanical properties however aem s can withand a wider temperature range than acm s and hydrogenated nitriles hnbr.

Ethylene acrylic rubber is a ethylene methyl acrylate polymer with a small amount of monomer containing carboxylic acid groups.
Water resistance is poor as is its resistance to acids and alkalis.
Acrylic rubber acm is a specialty synthetic rubber used when resistance to petroleum fuel oil oxygen ozone and heat are required.
Unlike butadiene based rubbers sbs nbr acrylic elastomers have good resistance to mineral oils oxygen ozone ultraviolet radiation and withstand higher temperatures.
