Elastomer Service Properties: HNBR
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) | tr10 temp C |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| HNBR | general | Fair | DH (ASTM D2000) | Hydrogenated C-C double bonds give superior heat and ozone resistance vs NBR while retaining excellent oil resistance; high tensile and abrasion resistance | Hydrogenated Nitrile | <30 | 150 | 70 | peroxide | 1.30-1.40 | 200-450 | Good | Low | -25 to -20 | 50-90 | 165 | 180 | 165 | -40 | Zetpol (Zeon), Therban (LANXESS); used in automotive timing belts, oil field seals | Excellent | Good | Poor | 20-31 | -35 to -30 |
| HNBR | high_sat | Good | DH (ASTM D2000) | Near-fully saturated backbone; maximum ozone and heat resistance; used in dynamic applications requiring long service life | HNBR High Saturation (>99%) | 15-25 | 150 | 70 | peroxide | 1.30-1.40 | 200-400 | Good | Low | -25 to -18 | 60-90 | 150 | 170 | 150 | -35 | Therban XT or Zetpol 2000 class; saturation >99% | Excellent | Excellent | Poor | 20-31 | -30 to -25 |
