Rubber: Rubber is an organic polymer with a molecular weight of several hundred thousand. It needs to be processed through vulcanization to maintain high elasticity within the temperature range (-50～150℃). Low modulus of elasticity, 3 orders of magnitude lower than ordinary materials, large deformation, elongation can reach 1000% (less than 1% for general materials), heat is released during stretching, and elasticity increases with temperature, which is also lower than that of general materials in contrast.
TPU: Thermoplastic elastomer is the general term for tpu, which is an environmentally friendly non-toxic polymer material. The tpu material combines the advantages of the high elasticity of rubber and the processing performance of plastics. It does not require vulcanization and can be processed by a general thermoplastic molding machine. In simple terms, the thermoplastic elastomer tpu is thermoformed, using an injection molding machine, an extruder, Blow molding machine can be produced. Waste and leftover materials can be 100% recycled, which is the preferred raw material to replace pvc, rubber, and silicone, and dominate the rubber and plastic industry.
