Rubber materials are widely used in industrial applications for sealing, shock absorption, protection and other functions in high temperature environments. Different types of rubber due to their chemical structure and formula design differences, its high temperature resistance is also different. The following are the high temperature limit temperatures of various common rubber:
Nitrile Rubber (NBR)
Maximum temperature limit: 120°C (248°F)
Features: Nitrile rubber has excellent oil resistance and wear resistance, often used in the manufacture of oil seals, O-rings, gaskets and so on.
Hydrogenated Nitrile Rubber (HNBR)
Maximum temperature limit: 150°C (302°F)
Features: Hydrogenated nitrile butadiene rubber is a modified product of nitrile butadiene rubber, with better heat resistance, oxidation resistance and chemical corrosion resistance.
Fluorocarbon Rubber (FKM)
Maximum temperature limit: 200°C (392°F)
Features: Fluorine rubber has excellent high temperature resistance, oil resistance and chemical corrosion resistance, widely used in aerospace, automotive and chemical industries.
4. Silicone Rubber (VMQ)
Maximum temperature 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.
Ethylene Propylene Rubber (Ethylene Propylene Rubber, EPM/EPDM)
Maximum temperature limit: 150°C (302°F)
Features: Ethylene propylene rubber has excellent weather resistance and ozone resistance, widely used in automotive, construction and water treatment and other fields.
6. Neoprene (CR)
Maximum temperature limit: 120°C (248°F)
Features: Neoprene rubber has good oil resistance, weather resistance and ozone resistance, and is often used in the manufacture of rubber pipes, seals and shock absorbers.
7. Natural Rubber (NR)
Maximum temperature limit: 80°C (176°F)
Features: Natural rubber has good elasticity, tear resistance and wear resistance, but its heat resistance is poor, generally used in low temperature and room temperature environment.
Polyurethane Rubber (PUR)
Maximum temperature limit: 90°C (194°F)
Features: Polyurethane rubber has excellent wear and oil resistance, but its heat resistance is relatively low, often used in the manufacture of seals, conveyor belts and tires.
Fluorosilicone Rubber (FVMQ)
Maximum temperature limit: 200°C (392°F)
Features: fluorine silicone rubber combines the advantages of silicone rubber and fluorine rubber, with excellent high temperature resistance and chemical corrosion resistance.
Acrylate Rubber (ACM)
Maximum temperature limit: 180°C (356°F)
Features: Acrylic rubber has excellent oil resistance and high temperature resistance, often used in the sealing of automotive engine parts.
conclusion
Different types of rubber materials have different high temperature resistance properties due to their chemical structure and formula design differences. 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 seals at high temperatures. By understanding the high temperature limit temperature of various types of rubber, it is possible to better select and apply the appropriate materials, thereby improving the reliability and safety of the system.
