Elastomer Service Properties: ACM
Service temperature limits, chemical resistance ratings, mechanical properties, and cure data for engineering elastomers and rubber compounds
| elastomer | grade or variant | acid resistance | astm designation | chemical resistance notes | common name | compression set pct (%) | compression set temp C | compression set time hr | cure system | density g cm3 (g/cm3) | elongation at break pct (%) | fuel resistance | gas permeability | glass transition temp C (C) | hardness range shore a | max continuous temp C (C) | max peak temp C (C) | max service temp C (C) | min service temp C (C) | notes | oil resistance | ozone resistance | steam resistance | tensile strength mpa (MPa) | volume swell oil irm903 pct |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| ACM | HT_ACM | Poor | DF, DH, EH (ASTM D2000) | Same as general ACM; HT-ACM grades developed for higher continuous service temperature while maintaining oil resistance and compression set | Polyacrylate (High Temperature) | 5-60 | 150 | 70 | chlorine or dual cure | 1.30 | 150-250 | Poor | Low | -42 to -18 | 50-80 | 175 | 200 | 175 | -40 | HyTemp HT-ACM series; improved low-temperature flexibility vs standard ACM; suitable for next-generation automatic transmissions | Excellent | Excellent | Poor | 7-14 | 10-60 |
| ACM | general | Poor | DF, DH (ASTM D2000) | Excellent resistance to hot mineral oils, ATF, and engine oils at elevated temperatures; not resistant to hot water, steam, fuels, polar solvents, aromatics, glycol brake fluids, acids, alkalis, amines | Polyacrylate (General) | <25 | 150 | 70 | diamine or soap/sulfur | 1.05-1.10 | 150-400 | Poor | Low | -40 | 45-80 | 150 | 180 | 150 | -20 | Ethyl acrylate copolymer; trade names HyTemp (Zeon), Nipol AR; niche between NBR and FKM for hot oil sealing; mainly automotive transmission and crankshaft seals | Excellent | Excellent | Poor | 7-14 | 10-60 |
