ACM
ACM (Acrylic Rubber)
Heat- and oil-resistant elastomer commonly used for drivetrain, lubricant, and industrial oil exposure.
回答型サマリー
- Temperature Range: -20 C to +175 C, compound-dependent
- Media Profile: Hot oils, lubricants, and selected transmission fluids
- Engineering Role: A practical hot-oil material between NBR/HNBR and FKM
適合条件
Best fit when hot oil aging is the main risk and FKM performance would be excessive for the project economics.
主な適用領域
Hot oil seals
Transmission-adjacent molded parts
Lubricant-contact gaskets
