Chemical name: Paste PVC Resin CAS No.: 9002-86-2 Molecular formula: [C2H3Cl]n Due to the fine particle size, the PVC paste resin has a texture like talcum powder and is immobile. Polyvinyl chloride paste resin is mixed with plasticizer to form a stable suspension after stirring, which is called PVC paste, or PVC plastisol, PVC sol, and it is used in this form to process the final product. In the process of paste making, various fillers, diluents, heat stabilizers, foaming agents and light stabilizers are added according to the needs of different products. The development of the PVC paste resin industry provides a new type of liquid material that can be turned into polyvinyl chloride products only by heating. This kind of liquid material is easy to configure, stable in performance, easy to control, easy to use, excellent in product performance, good in chemical stability, has certain mechanical strength, easy to color, etc., so it is widely used in artificial leather, vinyl toys, soft trademarks, Production of wallpaper, paint coatings, foamed plastics, etc. Compared with the traditional suspension resin, PVC paste resin has the following advantages: (1) The processing equipment is cheap. (2) The mold is simple and cheap. (3) Special shapes can be made. (4) Foaming is easy. (5) The products are heated less frequently, and can be produced in small quantities and in many varieties. PVC paste resin (PVC) is a large category of polyvinyl chloride resins. Compared with suspension resins, it is a highly dispersible powder with a particle size range of 0.1 to 2.0 m. ).
