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 Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.

As a construction additive, redispersible latex powder has been increasingly used in various fields of construction. But ten years ago, the product market was monopolized by foreign brands.
Changzhou Wanjia Drying Equipment Co., Ltd. has already started this research in 2002, constantly listening to users' opinions in production, and constantly improving in practice. In this technology, Changzhou Wanjia Drying Equipment Co., Ltd. has achieved a leading position in the industry.
At present, the re-dispersible emulsion powder equipment produced by Changzhou Wanjia Drying Equipment Co., Ltd. can support continuous production and has been put into use by domestic users such as Henan Tiansheng Chemical.
Recently, Changzhou Wanjia Drying Equipment Co., Ltd. has relied on its own scientific research strength to solve the technical problems of sticky-wall and pipeline blockage caused by the production of redispersible emulsion powder emulsion in the past seven years and achieved redispersibility. Domestic production of latex powder production equipment.
