Low temperature applications are limited to 10 c.
Acrylic rubber properties.
These polymers are usually prepared by emulsion or suspension polymerization.
Unlike butadiene based rubbers sbs nbr acrylic elastomers have good resistance to mineral oils oxygen ozone ultraviolet radiation and withstand higher temperatures.
Both have similar mechanical properties however aem s can withand a wider temperature range than acm s and hydrogenated nitriles hnbr.
It is also resistant to ozone and weathering and in these respects it is much superior to nitrile rubber.
Acrylic rubber is a type of synthetic rubber containing acrylonitrile.
Vamac also helps provide longevity in powertrain applications and air management systems and delivers long term durability in other environments with diverse chemical exposure.
Water resistance is poor as is its resistance to acids and alkalis.
Rubber material selection guide acm or polyacrylate acrylic rubber abbreviation acm astm d 2000 classification df dh chemical definition copolymer ethyl butyl acrylate 12 0000 series physical mechanical properties durometer or hardness range 40 90 shore a tensile strength range 500 2 500 psi elongation range 100 450.
The main repeat units are ethyl and butyl acrylate or a blend of both.
The chemical name of this rubber is alkyl acrylate copolymer.
Acrylic rubber acm is a specialty synthetic rubber used when resistance to petroleum fuel oil oxygen ozone and heat are required.
Acrylic rubber acm noxtite pa.
The outstanding property of this rubber is its resistance to hot oil and to oxidation.
Ethylene acrylic rubber is a ethylene methyl acrylate polymer with a small amount of monomer containing carboxylic acid groups.
Acm polyacrylic rubber properties.
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 generally resistant to ozone extreme pressure lubricants hot oils petroleum solvents animal and vegetable fats.
These properties especially the low oil swell allow rubber part makers better lifetime expectations.
The key properties of polyacrylic acm are its resistance to hot hydraulic oil and oxidation.
Acm polyacrylic 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.
