PVC additives are a kind of auxiliaries which can improve the processing properties of resins. The ductility of Polyvinyl chloride (PVC) melt is poor, which leads to melt breakage easily. Polyvinyl chloride melt relaxation is slow, easy to lead to rough surface, mat and "shark skin". Therefore, polyvinyl chloride processing often need to add processing aid to improve its melt defects.

Polyvinyl chloride mixtures are usually processed with a variety of processing AIDS. Different types of PVC additives can be used together to achieve better processing performance. For example, lubrication processing aid are usually used together with other types of PVC additives, which can be used in the production of blow molding vessels, calendering or extrusion sheet, wall panels, profile extrusion, high flow injection molding parts, pipe fittings, pipe wrapping and many other aspects. The balance between rheological properties of melt, homogeneity of melt and thermal demoulding properties of metal not only affects the appearance quality, but also affects the production efficiency. Whether the dosage of each component is appropriate is very important, it will affect the quality of the product, transportation and storage must be moisture-proof, sun protection and anti-fouling.
