As the name implies, polyvinyl chloride (PVC) paste resin is mainly used in the form of paste. People often call this paste plastisol, which is a unique liquid form of unprocessed polyvinyl chloride plastic. Paste resin is often made by emulsion and microsuspension method.

Polyvinyl chloride paste resin has fine particle size and its texture is like talcum powder, which has non-flowability. Polyvinyl chloride paste resin is mixed with plasticizer and stirred to form a stable suspension, that is, PVC paste, or PVC plastisol, PVC sol, and people use it in this form to process into final products. 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 PVC paste resin industry provides a new type of liquid material that can be transformed into polyvinyl chloride products only by heating. This liquid material is easy to configure, has stable performance, is easy to control, easy to use, has excellent product performance, good chemical stability, has certain mechanical strength, is easy to color, etc., so it is widely used in the production of artificial leather, vinyl toys, soft trademarks, wallpaper, paint coatings, foamed plastics, etc.

Introduction

Compared with traditional suspension resins, paste resins have the following advantages: (1) Cheap processing equipment. (2) Simple and cheap molds. (3) Can be made into special shapes. (4) Easy to foam. (5) Products are heated less times and can be produced in small quantities and in multiple varieties.

Paste resins are mainly used in the following ways:

Artificial leather industry: The overall market supply and demand are balanced. However, affected by the development of PU leather, the demand for artificial leather in Wenzhou and other major paste resin consumption areas is subject to certain restrictions. The competition between PU leather and artificial leather is relatively fierce.

Floor leather industry: Affected by the shrinking demand for floor leather, the demand for paste resins in this industry has been declining year by year in recent years.

Glove material industry: The demand is large, mainly imported, and it belongs to processing with supplied materials. In recent years, some Chinese manufacturers have been involved in the glove material industry, not only partially replacing imports, but also the sales volume is increasing year by year. Since the Chinese medical glove market has not yet been opened and no fixed consumer group has been formed, there is still a lot of room for the development of medical gloves.

Wallpaper industry: With the continuous improvement of people's living standards, the development space of wallpaper, especially high-end decorative wallpaper, is constantly expanding. For example, the demand for wallpaper in hotels, entertainment venues and some home decorations is constantly expanding.

Toy industry: The market demand for paste resin is relatively stable.

Dip molding industry: The demand for paste resin is increasing year by year; for example, high-end dip molding is mainly used in electric handles, medical devices, etc.

Conveyor belt industry: The demand is stable but the benefits of downstream enterprises are not good.

Automotive decoration materials: With the rapid development of China's automobile industry, the demand for paste resin for automotive decoration materials is also expanding.
