Plasticization is the process of changing the structure of a polymer to make it easier to bend.The application of heat on thermoplastic polymers will result in plasticization.Internal plasticization of a rigid polymer can be carried out by chemically modifying the polymer or the monomer so that the flexibility of the polymer is increased.Plasticization is the process of changing the structure of a polymer to make it easier to bend.

1.The effect of plasticization on product performance:The degree of plasticization of PVC hard goods is between 60% and 70%. Excessive or too low degrees of plasticization will affect the physical and other properties of the products.

more details：

1)when the degree of plasticization is 60%, the tensile strength is the highest;

2)when the  degree of plasticization is 65%, the impact strength is the highest;

3)when the  degree of plasticization is 70%, the elongation at break is the highest;

For the production of water supply pipe material, plasticizing degree of 60-65%

2. The effect of temperature on ductility:

The polymer material cannot be melted at a temperature lower than 80 ° C. A glass or glass material is hard and brittle, and cannot be processed in the glass material; as the temperature rises to 160 ° C, the material is in a highly elastic state. However, in the area of the material or when it does not flow, it can only soften the material and increase the viscoelasticity; and it can really achieve the melt processing of PVC, the temperature should be between 160-200 degrees, but for any long-term heat stabilizer For example, at temperatures above 200 degrees, and the decomposition of materials, therefore, in controlling the degree of plasticization, the following points should be noted: the temperature can only be controlled between 160-200 degrees Celsius. In the temperature range of 40 ° C, when the temperature of PVC is set at 170-180 ° C, the plasticizing effect is better.
