The main range of performance indicators: tensile strength 25 ~ 34MPa, elongation 830% ~ 890%, elastic modulus 27 ~ 30MPa, tear strength of 42 ~ 75KN / M, wear 28mm3, resilience 40% ~ 64%. Even after a few years of aging test or after using it, it can maintain good performance. Especially suitable for automotive interior parts, with high quality, high strength, long life characteristics.
