The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC and additives are mixed and plasticized, a three-roll or four-roll calender is used to form a transpare

Among the many PVC products, PVC pipes are its second largest consumption area, accounting for about 20% of its consumption. In my country, PVC pipes are developed earlier than PE pipes and PP pipes,

Profiles and profiled materials are the largest areas of PVC consumption in my country, accounting for about 25% of the total PVC consumption. They are mainly used to make doors and windows and energy

The polyvinyl chloride melt is a non-Newtonian pseudo-fluid. The larger the shear rate, the smaller the apparent viscosity, and the change is quite sensitive. When the temperature is raised, the visco

The glass transition temperature (Tg) is only related to the molecular chain segment structure, and has little to do with the molecular weight, while the viscous flow temperature (Tf) is the temperatu

Polyvinyl chloride plastics have different shapes and differences, and there are various processing methods, such as pressing, extrusion, injection, coating, etc. The particle size, fish eye, bulk den
