How to increase the degree of plasticization of PVC products?

 

1 Effect of plasticization on product performance:

The performance of PVC products is closely related to the degree of plasticization, the degree of plasticization is poor, the products are brittle, the mechanical properties cannot meet the requirements, however if the degree of plasticization is too high, the product will appear yellow lines, the mechanical properties are unqualified. So the degree of plasticization is very important in the Processing of PVC Products.

a. When the degree of plasticization is 60%, the tensile strength is the highest;

b. When the degree of plasticization is 65%, the impact strength is the highest;

c. When the degree of plasticization is 70%, the breaking elongation is the highest;

 

For the production of water pipe material plasticity of 60-65% is the most appropriate. Because it can reflect both tensile strength and impact strength in this range.
