Elastomer Material Properties & Applications
1. Aflas® / Kalrez® (FFKM, Perfluoroelastomer)
Features: Outstanding broad chemical resistance, withstands nearly all solvents, acids, bases, plasma, and high temperatures; ultra-low outgassing, excellent heat stability, low compression set, and premium inertness. High cost.
Applications: Semiconductor equipment, chemical processing, oil & gas, pharmaceutical seals, aerospace, and critical high-purity and aggressive media sealing.
2. Acrylate Rubber (ACM / Polyacrylate Rubber)
Features: Excellent resistance to hot oil, lubricants, and oil additives; great ozone and weather aging resistance; limited low-temperature performance; susceptible to hydrolysis and hot water.
Applications: Automotive powertrain, transmission oil seals, under-hood gaskets, and O-rings for high-temperature oil circuits.
3. Butyl Rubber (IIR)
Features: Extremely low gas permeability among all rubbers; excellent vibration damping; good ozone and weather resistance; poor oil resistance.
Applications: Vacuum seals, inner tubes, medical stoppers, gas tank liners, shock mounts, and air-tight gaskets.
4. Ethylene-Propylene (EPR / EPDM)
Features: Excellent ozone, UV, and weather resistance; good hot water and steam resistance; resistant to dilute acids and alkalis; poor oil resistance.
Applications: Water treatment, HVAC, plumbing, automotive cooling systems, outdoor machinery, and sanitary equipment sealing.
5. Ethylene Acrylate Rubber (AEM)
Features: Good heat, oil, ozone, and weather resistance; better hydrolysis resistance than ACM; low compression set; stable at elevated temperatures.
Applications: Automotive engine seals, turbocharger hoses, oil pan gaskets, power steering, and transmission sealing parts.
6. Fluorocarbon (FKM / FPM)
Features: Superior heat, oil, fuel, and chemical resistance; excellent aging and ozone resistance; low gas permeability; not suitable for ketones, esters, and hot steam in many grades.
Applications: Petrochemical, automotive fuel systems, hydraulic equipment, heavy industry, aerospace high-temperature seals, and valve & pump O-rings.
7. Fluorosilicone (FVMQ)
Features: Combines silicone's wide temperature range with moderate fuel and oil resistance; good low-temperature flexibility and electrical insulation; limited mechanical strength.
Applications: Aerospace fuel systems, aircraft seals, automotive fuel vapor components, and low-temperature oil-resistant sealing gaskets.
8. Hydrogenated Nitrile (HNBR)
Features: Saturated NBR with much better heat, ozone, and aging resistance than standard NBR; excellent abrasion and tear strength; resistant to sour oil and H₂S; low compression set.
Applications: Oilfield equipment, automotive engine seals, hydraulic seals, drilling machinery, and high-performance dynamic sealing.
9. Neoprene Rubber (CR / Chloroprene Rubber)
Features: Balanced general-purpose rubber; good ozone, weather, and flame resistance; moderate oil resistance; good water resistance; stable physical properties.
Applications: Marine seals, cable gaskets, refrigeration equipment, hoses, construction joints, and general industrial sealing parts.
10. Nitrile Rubber (Buna-N / NBR)
Features: Excellent mineral oil and fuel resistance; good mechanical strength and wear resistance; cost-effective; poor ozone and weather resistance.
Applications: Hydraulic systems, automotive lubrication and fuel circuits, pumps, valves, and general oil-sealing O-rings and gaskets.
11. Natural Rubber (NR)
Features: Ultra-high tensile strength; outstanding resilience and tear resistance; excellent shock absorption and flexibility; poor oil, ozone, and UV resistance.
Applications: Vibration mounts, shock pads, dust seals, agricultural machinery, dynamic buffer components, tires, and conveyor parts.
12. Polyurethane (PU)
Features: Exceptional abrasion resistance, high tear strength, high extrusion resistance, and good wear performance; higher hardness options available; limited hydrolysis resistance.
Applications: Heavy-duty dynamic seals, hydraulic rod seals, wear pads, rollers, impact bumpers, and mining machinery sealing parts.
13. Silicone Rubber (VMQ)
Features: Extremely wide temperature range (-60°C to 200°C); good ozone, UV, and weather resistance; non-toxic; excellent electrical insulation; poor oil resistance.
Applications: Food and medical equipment, home appliance gaskets, oven and sealer seals, outdoor lighting, sanitary, and high-temperature static seals.
14. Styrene-Butadiene Rubber (SBR)
Features: Good abrasion resistance, low cost, stable performance with brake fluid and water; inferior ozone and oil resistance compared to many elastomers.
Applications: Brake system seals, belts, hoses, general gaskets, tire components, and low-cost non-oil sealing parts.
