Polyvinyl chloride products are mainly used for packaging of various containers, films and rigid sheets. PVC containers are mainly used for the production of mineral water, beverage, cosmetic bottles,

Extruders can be used to extrude hoses, cables, wires, etc.; injection molding machines can be used with various molds to make plastic sandals, soles, slippers, toys, auto parts, etc.

Stabilizers, lubricants and fillers are added to PVC. After mixing, hard pipes, special-shaped pipes and corrugated pipes of various diameters can be extruded by an extruder, which can be used as sewe

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 were developed earlier than PE pipes and PP pipes,

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

Therefore, for some processing molding (such as injection molding), it is necessary to appropriately reduce the molecular weight of the resin. According to the size of the molecular weight, domestic s

Below the glass transition temperature (Tg, 80°C), polyvinyl chloride is in a glass state; at Tg→viscous flow temperature (Tf, about 160°C), it is highly elastic and rubbery, and has plasticity; at Tf

Polyvinyl chloride is an amorphous high polymer with low shrinkage. The powder should be preheated before processing to remove moisture, enhance the plasticizing effect and prevent air bubbles. Moreov

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

It is one of the plastic products with the largest output in the world, it is cheap and widely used, and the polyvinyl chloride resin is white or light yellow powder. Different additives can be added

The biggest feature of PVC is flame retardant, so it is widely used in fire protection applications. But PVC releases hydrogen chloride and other toxic gases such as dioxins when it burns. The combust
