Low temperature applications are limited to 10 c.
Acrylic rubber properties.
It is generally resistant to ozone extreme pressure lubricants hot oils petroleum solvents animal and vegetable fats.
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.
Acm polyacrylic rubber.
Vamac also helps provide longevity in powertrain applications and air management systems and delivers long term durability in other environments with diverse chemical exposure.
These properties especially the low oil swell allow rubber part makers better lifetime expectations.
Ethylene acrylic rubber is a ethylene methyl acrylate polymer with a small amount of monomer containing carboxylic acid groups.
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.
The key properties of polyacrylic acm are its resistance to hot hydraulic oil and oxidation.
Both have similar mechanical properties however aem s can withand a wider temperature range than acm s and hydrogenated nitriles hnbr.
These polymers are usually prepared by emulsion or suspension polymerization.
Acrylic rubber acm noxtite pa.
Acm is polar and doesn t contain unsaturation.
The chemical name of this rubber is alkyl acrylate copolymer.
Acm polyacrylic rubber properties.
Unlike butadiene based rubbers sbs nbr acrylic elastomers have good resistance to mineral oils oxygen ozone ultraviolet radiation and withstand higher temperatures.

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.
Today s engine and transmission requirements would be difficult to meet cost effectively without acm.
It is also resistant to ozone and weathering and in these respects it is much superior to nitrile rubber.
The main repeat units are ethyl and butyl acrylate or a blend of both.
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.
