    Chemdo Description About Pvc Paste Resin

    Polyvinyl chloride (PVC) paste resin as the name suggests is that this resin is mainly used in the form of paste. People often call this paste plasticized paste. It is a unique liquid form of PVC plastic in the unprocessed state. Paste resins are often obtained by emulsion and micro suspension.

    Due to its fine particle size, PVC paste resin is like talc powder and has no fluidity. PVC paste resin is mixed with plasticizer and stirred to form a stable suspension, that is, PVC paste, or PVC plasticized paste and PVC sol, which is used to process into final products. In the paste making process, 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 PVC products only by heating. The liquid material has the advantages of convenient configuration, stable performance, easy control, convenient use, excellent product performance, good chemical stability, certain mechanical strength, easy coloring, etc. Therefore, it is widely used in the production of artificial leather, enamel toys, soft trademarks, wallpaper, paint coatings, foamed plastics, etc.
