| Natural Rubber (NR) | 40–80 | About −40 to +80 °C | High resilience, tensile strength, and resistance to repeated impact and abrasion; effective for vibration isolation. | Machine mounts, impact pads, conveyor components, and general vibration-control pads. | Limited resistance to oils, ozone, weathering, and many chemicals; protect it from prolonged outdoor exposure. |
| Styrene-Butadiene Rubber (SBR) | 50–80 | About −40 to +100 °C | Good abrasion resistance and mechanical strength at a practical cost; suitable for general-purpose cushioning. | Floor protection, general-purpose gaskets, anti-vibration pads, and industrial lining. | Not a preferred choice for sustained contact with oils, fuels, or strong outdoor ozone exposure. |
| Nitrile Rubber (NBR) | 40–90 | About −30 to +100 °C | Good resistance to petroleum oils, greases, and many fuels; hardness and formulation affect wear and flexibility. | Oil-resistant machine pads, seals, pump components, and workshop equipment supports. | Ozone, sunlight, and weather resistance are generally limited unless the compound is specially protected. |
| EPDM Rubber | 40–80 | About −40 to +120 °C | Strong resistance to weathering, ozone, water, and many dilute acids and alkalis; maintains flexibility outdoors. | Outdoor equipment pads, water-system seals, weather-exposed supports, and electrical enclosures. | Generally unsuitable for petroleum oils, fuels, and many hydrocarbon-based fluids. |
| Chloroprene Rubber (CR, commonly called Neoprene) | 40–80 | About −30 to +100 °C | Balanced resistance to weather, ozone, moderate oils, and abrasion; useful where several properties are needed. | Outdoor machine mounts, bridge and structural bearing pads, gaskets, and vibration isolators. | Compatibility with specific chemicals and oils depends on the fluid, temperature, and compound formulation. |
| Silicone Rubber | 30–80 | About −55 to +200 °C | Retains flexibility across a wide temperature range and offers good heat and weather resistance. | Heat-exposed equipment cushioning, thermal-interface pads, and selected sealing applications. | Often has lower tear and abrasion resistance than tougher industrial elastomers; check load and wear requirements. |
| Fluoroelastomer (FKM) | 60–90 | About −20 to +200 °C | High resistance to many oils, fuels, and aggressive chemicals, with good performance at elevated temperatures. | Process-equipment seals, chemical-service pads, and components exposed to hot oils or fuels. | Typically more costly; low-temperature flexibility and compatibility with hot water or steam depend on the grade. |
| Butyl Rubber (IIR) | 40–70 | About −40 to +120 °C | Very low gas permeability and good resistance to ozone and weathering; provides useful damping. | Sealing pads, vibration-damping components, and applications requiring reduced gas transmission. | Not generally suited to petroleum oils and fuels; check the compound for the intended chemical environment. |
| Hydrogenated Nitrile Rubber (HNBR) | 50–90 | About −30 to +150 °C | Improved heat, aging, and mechanical performance compared with standard NBR, while retaining useful oil resistance. | Oilfield equipment, automotive and industrial seals, and supports exposed to heat and mechanical stress. | Performance varies by grade; confirm compatibility with the exact fluid, temperature, and duty cycle. |
| Cork-Rubber Composite | Typically specified by density and compression rather than Shore A | Often about −20 to +100 °C | Compressible composite that can seal uneven surfaces and help damp vibration; available with different cork contents and binders. | Equipment gaskets, enclosure seals, low-pressure cushioning, and vibration-isolating pads. | Load capacity, fluid resistance, and recovery after compression depend strongly on the binder and composite construction. |
