The main characteristics of PET are: a wide range of hardness: by changing the proportion of PET reaction components, products of different hardness can be obtained. With the increase of hardness, the products still maintain good elasticity and wear resistance. High mechanical strength: PET products have excellent bearing capacity, impact resistance and shock absorption. Excellent cold resistance: PET has a relatively low glass transition temperature and maintains good elasticity, flexibility and other physical properties at minus 35 degrees Celsius. Good processing performance: PET can be processed by conventional thermoplastic processing methods, such as injection molding, extrusion, calendering, etc. At the same time, PET can be processed with certain polymer materials to obtain polymer alloys with complementary properties. PET is resistant to oil, water and mold. Good recovery.
