Kunshan PVC resin molding products methods have a few?

What is the influence of the viscosity value (mL/g) of Kunshan PVC resin on the molding products?

The choice of viscosity value of PVC resin is related to the molding products, which directly affects the physical and mechanical properties of plastic products. Resin with low viscosity, good fluidity of molten material, easy to process and form, and can be formed under low temperature conditions.

This resin is mainly used to form hard plates, records, dura and parts of plastic products. The high viscosity of the resin of raw materials, melting fluidity is poor, molding products are also more difficult, mainly used to form soft film, cable sheath and shoe plastic products. PVC resin molding products methods have a few?

Methods of polyvinyl chloride molding plastic products are:

(1) Calendering molding method - forming plastic film, sheet, plate and artificial leather surface layer on calendering machine;

Extrusion molding method - Ⅲ Extruder molding pipe, plate, hose and blown film products;

(3) Injection molding method: plastic products such as pipe fittings, electrical parts, basins, boxes and machine parts are injected into the plastic products by injection molding machines.
