What is the difference between molding materials
In life, we can see that many connectors are covered with a layer of plastic, but there are also direct wiring. But it seems that plastic ones are safer, so how do you make plastic connectors? In fact, it is through injection molding. What kinds of molding materials are there? PVC is more commonly used, but some people use tpu. What is the difference between these two molding materials? The characteristics of TPU: TPU has excellent high tension, high tensile strength, toughness and aging resistance characteristics, is a mature environmental protection material. It has the characteristics of high strength, good toughness, abrasion resistance, cold resistance, oil resistance, water resistance, aging resistance, and weather resistance unmatched by other plastic materials. At the same time, it has high water resistance and moisture permeability, wind resistance, cold resistance, antibacterial, mildew resistance, Many excellent functions such as warmth, anti-ultraviolet and energy r...
