Introduction to Acrylic Rubber (ACM, AEM)-SKY RUBBER

Acrylic rubber ( ACM ) is copolymerized from acrylate monomers. Its main chain is a saturated carbon chain, and its side groups are polar ester groups. It has advantages such as simple processing equipment and ease of implementation.

Performance characteristics :

Advantages: It is heat-resistant, aging-resistant, oil-resistant, ozone-resistant, and UV-resistant. Its mechanical properties and processing properties are superior to fluororubber and silicone rubber, and its heat resistance, aging resistance, and oil resistance are superior to nitrile rubber.

Disadvantages: Not resistant to low temperatures, not resistant to water, relatively difficult to process, and not resistant to alkaline environments.

Main uses :

ACM is widely used in various high-temperature and oil-resistant environments, and has become a sealing material that the automotive industry has focused on developing and promoting in recent years, especially for high-temperature oil Seals, crankshafts, valve stems, cylinder head gaskets, hydraulic oil lines, etc.

Ethylene acrylate rubber ( AEM ) is a copolymer of ethylene, methyl acrylate, and carboxylic acid monomers. Its main chain is a saturated carbon chain, and its side groups are polar ester groups. It has the advantages of simple processing equipment and ease of implementation.

Performance characteristics :

Excellent heat aging resistance and liquid resistance; its heat resistance is superior to chlorosulfonated polyethylene rubber ( CSM ) and NBR . AEM rubber has good resistance to ATF , gear oil, and ethylene glycol / water mixtures, but poor resistance to gasoline and phosphate ester hydraulic oils. Low oil swelling rate and high wear resistance.

Main uses :

Seals, gaskets, rocker arm cover seals, transmission oil cooling hoses, valves, dampers, shock absorbers; seals, sleeves, diaphragms, bellows, etc. for automotive powertrain systems.
