Advantages and disadvantages of polyacrylate rubber ACM and its temperature resistance performance

🕙 2023-09-28 👆

Polyacrylate rubber (ACM) is an elastomer obtained by copolymerization of acrylic ester as the main monomer. Its main chain is a saturated carbon chain, and its side groups are polar ester groups. Due to its unique structure, it has many excellent characteristics, such as heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance, etc. Its mechanical and processing properties are superior to fluororubber and silicone rubber, and its heat resistance, aging resistance, and oil resistance are superior to nitrile rubber. ACM is widely used in various high-temperature and oil-resistant environments and has become a sealing material that has been heavily developed and promoted in the automotive industry in recent years, especially for high-temperature oil seals, crankshafts, valve stems, cylinder gaskets, hydraulic oil pipelines, etc. used in automobiles.

Advantages: resistant to petrochemical oil, high temperature, good weather resistance, good oxidation resistance, resistance to bending deformation, and excellent resistance to oil products.

General operating temperature range: -25-170 ℃

Disadvantages: Not suitable for hot water, brake oil, phosphate esters, and not resistant to low temperatures. Mechanical strength, compression deformation rate, and water resistance are relatively weak, which are worse than general oil resistance

Commonly used in: automotive transmission oil, automotive transmission system and power steering wheel, and power system seals.
