In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
The production process of PVC Resin SG8 and PVC RESIN SG5 is basically the same, and the production equipment is exactly the same. The main difference lies in the formulation of additives, polymerization temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of the polymerizer. The reaction requirements are relatively strict, and the requirements on operation, safety, technology, and personnel quality are more stringent, and the resin quality is more difficult to control.

The production and sales data for the first quarter of this year showed that Foton Motor's performance in the first quarter rose by more than 10% year-on-year, squeezing into the top three of the entire automotive industry.
According to industry sources, manufacturers such as FAW, Dongfeng, Futian and Changan have benefited from the warming of the commercial vehicle market in the first quarter. The overall target market for commercial vehicles at the beginning of the year increased slightly year-on-year, and the overall market gradually emerged from last year's “coolness†and finally showed signs of rejuvenation. Among them, the light-duty truck market still continues to grow steadily. Although the medium- and heavy-duty trucks experienced a slight drop from the same period of last year, they have shown a warming trend since March. It is undeniable that Chinese truck manufacturers’ resistance to “cold†is rapidly increasing, and the prospects for the truck market this year are promising.
