1. PVC profile Profiles and profiles 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 e
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
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 during combustion. The combustion of PVC
It has stable physical and chemical properties, is insoluble in water, alcohol, gasoline, and has low gas and water vapor leakage; at room temperature, it can withstand any concentration of hydrochlor
The natural color is light yellow, translucent and shiny. The transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the dosage of additiv

China's PVC resin consumption is mainly concentrated in South China and East China. The total consumption of Guangdong, Zhejiang, Fujian, Shandong and Jiangsu accounts for about 70.0% of the total nat
Polyvinyl chloride is a polar polymer and has a high affinity for conductive substances such as water, so its resistance is smaller than that of non-polar polyolefins, but it still has a higher volume
Weatherability refers to the ability of a pigment to withstand various climates. These include visible and ultraviolet light, moisture, temperature, atmospheric chlorination, and chemicals encountered
mobility Migration occurs only in plasticized PVC articles and when dyes or organic pigments are used. The so-called migration is that some soluble dyes or organic pigments existing in the surroundin
