| Natural Rubber (NR) | High elasticity, resilience, and resistance to repeated flexing; good vibration and impact absorption. | About 40–80 Shore A | Approximately −50°C to +80°C | Anti-vibration mounts, impact pads, general-purpose machine feet. | Poor resistance to oils, ozone, and prolonged outdoor weathering. |
SBR Styrene-Butadiene Rubber | Good abrasion resistance and mechanical strength; often used for economical general-purpose pads. | About 40–80 Shore A | Approximately −40°C to +100°C | Floor protection, equipment pads, and general industrial cushioning. | Limited resistance to oils, ozone, and outdoor aging unless specially compounded. |
EPDM Ethylene Propylene Diene Rubber | Strong resistance to weather, ozone, water, and many dilute acids and alkalis. | About 40–80 Shore A | Approximately −40°C to +120°C; some compounds are rated higher. | Outdoor equipment pads, sealing pads, and water-exposed applications. | Generally unsuitable for petroleum oils and many hydrocarbon fuels. |
NBR Nitrile Rubber | Good resistance to many oils, greases, and fuels; properties vary with acrylonitrile content. | About 40–90 Shore A | Approximately −30°C to +100°C | Oil-resistant machine pads, workshop equipment, and sealing or support pads. | Less suitable for ozone, sunlight, and high-temperature exposure than EPDM or silicone. |
CR Chloroprene Rubber (Neoprene-type) | Balanced mechanical properties with moderate oil resistance and good weather and flame-retardant potential in suitable formulations. | About 40–80 Shore A | Approximately −35°C to +100°C | General industrial pads, outdoor supports, and vibration-control components. | Not as oil-resistant as many NBR compounds or as weather-resistant as EPDM. |
| Silicone Rubber | Retains flexibility across a wide temperature range; good resistance to heat, ozone, and aging. | About 30–80 Shore A | Approximately −60°C to +200°C; grades may vary. | Heat-exposed supports, appliance pads, and applications requiring low-temperature flexibility. | Often has lower tear and abrasion resistance than general-purpose rubber compounds. |
| Polyurethane Elastomer (PU) | High abrasion, tear, and load-bearing resistance; available in a broad range of hardnesses. | About 60 Shore A to 70 Shore D | Often approximately −30°C to +80°C; formulation-dependent. | Heavy-duty wear pads, rollers, bumpers, and high-load support pads. | Some grades can be affected by hot water, humidity, or prolonged high-temperature service. |
