mechanical properties. Selecting the correct elastomer is essential for long-term performance.

Material Continuous Temperature Oil Resistance Typical Applications
NBR Up to 120°C Excellent Hydraulic & Fuel Seals
EPDM Up to 150°C Poor Outdoor Seals & HVAC Systems
Silicone Up to 200°C Fair Medical & Electronic Components
FKM Up to 220°C Excellent Automotive & Chemical Equipment

Besides temperature, engineers should also evaluate media compatibility, compression set, ozone resistance, pressure, and mechanical stress to ensure reliable long-term performance.

Solution

An effective high-temperature solution requires more than choosing a heat-resistant material. It involves proper material selection, compound formulation, precision molding, and rigorous quality verification under actual working conditions.

As an industry example, Ningbo Yongbo Rubber & Plastic Products Co., Ltd. specializes in customized rubber and plastic components for industrial applications. By offering application-based material recommendations, custom mold development, and strict manufacturing control, the company helps customers select suitable compounds such as NBR, EPDM, Silicone, or FKM according to temperature, media, and operating conditions. This engineering-driven approach improves sealing performance, extends product lifespan, and reduces maintenance costs in high-temperature environments.

Warning

Selecting rubber based only on its advertised maximum temperature is a common mistake. Continuous operating temperature, exposure to oil or chemicals, pressure, and long-term compression often determine actual service life. Always verify material performance through heat-aging, compression-set, and application-specific testing before mass production. Investing in the right material from the beginning can significantly improve reliability and lower total lifecycle costs.
