Grey PVC Plastic Rigid Sheet has excellent corrosion resistance and has become an environmentally friendly material unanimously praised by the public. Its raw materials are all very environmentally friendly materials. In addition, everyone is more concerned about its craftsmanship. Let me introduce it to you below. Process characteristics of plastic board:
The higher the degree of molecular orientation, the greater the shrinkage rate. Grey PVC Plastic Rigid Sheet，The viscosity of the melt decreases significantly with increasing shear rate. The plastic sheet does not need to be dried during processing, and the shrinkage and crystallinity are lower than that of the PE plastic sheet. Its processing temperature is preferably around 200-300 °C, and it has good thermal stability. Since the viscosity of the plastic sheet decreases significantly with the increase of the shear speed, increasing the injection pressure and injection speed will improve the fluidity, change the shrinkage deformation and depression, and the mold temperature should be controlled within the range of 30-50 °C.
Grey PVC Plastic Rigid Sheet is heat-resistant, impact-resistant, non-toxic, and odorless. It is one of the engineering plastics that meet the environmental protection requirements. its development.
