Are TPE and TPR cold resistant? In fact, the TPE soft material produced by Jiayang Boguan Company can withstand -50℃ low temperature, which is suitable for making diving equipment accessories, skiing equipment accessories (sheath), low-temperature-resistant hose and other products.

The real TPR material is not, its environmental use temperature is -40 degrees to -80 degrees, that is to say, as long as it does not exceed its limit value of -40 degrees, it will not become hard and brittle.

The biggest problem with SBS and SIS is that they are not heat resistant, and their service temperature generally cannot exceed 80 degrees Celsius. At the same time, its strong elongation, weather resistance, oil resistance, abrasion resistance, etc. can not be compared with rubber.

For this reason, in recent years, the United States and Europe and other countries it carried out a series of performance improvements, has appeared in SBS and SIS by saturated hydrogenation of SEBS and SEPS. SEBS (to BR hydrogenation for soft chain segment) and SEPS (to IR hydrogenation for soft chain segment) can make a substantial increase in the strength of the impact, weathering and heat aging resistance is also good.
