It is made of high-quality PP material with sufficient material. Different from the cheaper PE material on the market, among general-purpose plastics, PP has the best heat resistance, with a heat distortion temperature of 80-100℃, and can be boiled in boiling water. PP has excellent resistance to stress cracking and a high bending fatigue life, and is commonly known as "hundred-fold rubber". The operating temperature range is -30 to 140℃. The comprehensive performance of PP is superior to that of PE material. PP products are light in weight, have good toughness and excellent chemical resistance.
