Shanghai Pepsen manufactures heat resistance urethane rubber wheels, sheets, bushings and other parts as per customer requirements such as hardness, drawing and working environment. In general, long term working temperature of normal polyurethane is no higher than 80 degree C. Special formulations such as PPDI and NDI can reach up to as high as 150 degree C, but the cost is about several times of normal urethane. PEPSEN special formulated urethane can reach 160 degree C with very cost effective cost.

What is heat resistance urethane rubber?

Heat resistance (dynamic performance properties) is rarely mentioned for urethane rubber because it is the only disadvantage of urethane. Especially under the condition of high speed and high load, the build-up heat will destroy urethane quickly, that is why urethane is not used for car tire though abrasion resistance is much better than natural rubber.

Special formulations such as PPDI and NDI are usually used to avoid this disadvantage, but cost is much expensive.

PEPSEN chemical engineering staff has been doing research and testing on this field in past 15 years and we have developed urethane formulations that can working under 160 degree C, but the cost is much lower.
