What is PVC Paste Resin
PVC paste resin, also known as PVC emulsion resin, is an aggregate of latex particles with a particle size of 0.1 to 2.0 pm. It is white fine powder in appearance. After mixing the polyvinyl chloride with plasticizer, a stable suspension can be formed by stirring, which is made into PVC paste, PVC plastisol, or PVC sol. PVC emulsion resin is used in these forms to process into final products. In the process of making paste, 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 becomes a polyvinyl chloride product only by heating. This kind of liquid material is easy to configure, stable in performance, easy to control and use, excellent in product performance, good in chemical stability, easy to color, and also has certain mechanical strength. So it is widely used in water pipe, chemical pipe, PVC trunkings and plastic doors, cable wire, packing film, plastic carpet, plastic ceiling, sanitary fitting, plastic wall paper etc.
