Inventory of high temperature resistance limit temperature of various types of rubber

Rubber materials are widely used in industrial applications for sealing, shock absorption, protection and other functions in high temperature environments. Different types of rubber have different high temperature resistance due to differences in their chemical structure and formula design. The following are the high temperature resistance limits of various common rubbers:

1. Nitrile Rubber (Nitrile Rubber, NBR)

Maximum temperature resistance limit: 120°C (248°F)

Features: Nitrile rubber has excellent oil resistance and wear resistance, and is often used to manufacture oil seals, O-rings, gaskets, etc.

2. Hydrogenated Nitrile Rubber (HNBR)

Maximum temperature resistance limit: 150°C (302°F)

Features: Hydrogenated Nitrile Rubber is a modified product of nitrile rubber, with better heat resistance, oxidation resistance and chemical corrosion resistance.

3. Fluorocarbon Rubber (FKM)

Maximum temperature resistance limit: 200°C (392°F)

Features: Fluorocarbon rubber has excellent high temperature resistance, oil resistance and chemical corrosion resistance, and is widely used in aerospace, automotive and chemical industries.

4. Silicone Rubber (VMQ)

Maximum temperature resistance limit: 220°C (428°F)

Features: Silicone rubber has excellent high temperature resistance and low temperature resistance, and can maintain good elasticity in the temperature range of -60°C to 220°C.

5. Ethylene Propylene Rubber (EPM/EPDM)

Maximum temperature resistance limit: 150°C (302°F)

Features: Ethylene Propylene Rubber has excellent weather resistance and ozone resistance, and is widely used in automotive, construction and water treatment.

6. Neoprene (CR)

Maximum temperature resistance limit: 120°C (248°F)

Features: Neoprene has good oil resistance, weather resistance and ozone resistance, and is often used to make rubber tubes, seals and shock absorbers.

7. Natural Rubber (NR)

Maximum temperature resistance limit: 80°C (176°F)

Features: Natural rubber has good elasticity, tear resistance and wear resistance, but its heat resistance is poor, and it is generally used in low and normal temperature environments.

8. Polyurethane Rubber (PUR)

Maximum temperature resistance limit: 90°C (194°F)

Features: Polyurethane rubber has excellent wear resistance and oil resistance, but its heat resistance is relatively low, and is often used to make seals, conveyor belts and tires.

9. Fluorosilicone Rubber (FVMQ)

Maximum temperature resistance limit: 200°C (392°F)

Features: Fluorosilicone rubber combines the advantages of silicone rubber and fluororubber, and has excellent high temperature resistance and chemical corrosion resistance.

10. Acrylate Rubber (ACM)

Maximum temperature resistance limit: 180°C (356°F)

Features: Acrylate rubber has excellent oil resistance and high temperature resistance, and is often used for sealing of automotive engine components.

Conclusion

Different types of rubber materials have different high temperature resistance due to their differences in chemical structure and formula design. In practical applications, the selection of suitable rubber materials should be comprehensively considered according to the specific application environment and temperature requirements to ensure the performance and life of the seal at high temperatures. By understanding the high temperature resistance limit temperature of various types of rubber, it is possible to better select and apply suitable materials, thereby improving the reliability and safety of the system.
