Can TPE and TPR withstand cold
Nov 28, 2018

        In fact, TPE soft material can withstand - 50 C low temperature, suitable for diving equipment accessories, skiing sports equipment accessories (sheaths), low temperature hoses and other products.

  TPE materials are elastomeric plastics with rubber properties obtained by blending modification of SEBS and SBS elastomers. TPE materials have elasticity and wear resistance similar to rubber. TPE materials are transparent or natural plastic particles with specific gravity of 0.85-1.20 g/cubic centimeter. Its hardness and physical properties can be achieved by adjusting the composition and proportion of blending modification formula. Cheng.

  The ultra-low temperature resistance of TPE soft material depends on the microstructure of TPE material. Because TPE material has the characteristics of rubber, the glass transition temperature (Tg) of TPE soft material is very low, about - 50 ~ 60 C.

  True TPR materials have ambient temperatures ranging from minus 40 degrees to minus 80 degrees, which means that as long as they do not exceed the limit of minus 40 degrees, they will not harden or become brittle.

  Therefore, SEBS and SEPS are not only universal, but also blends used in engineering plastics to improve weather resistance, wear resistance and heat aging resistance. As a result, SEBS and SEPS have rapidly developed into "alloys" of engineering plastics such as nylon (PA), polycarbonate (PC).
