PVC Processing Aids To Improve Processing Performance

- Nov 23, 2018-

PVC additives are mainly used in PVC products such as PVC pipes, PVC profiles, PVC sheets, PVC cables, etc. The main function of PVC additives is to increase the amount of calcium carbonate powder to reduce production costs, and also to solve the poor fluidity of products, PVC The problem of decreased mechanical properties such as tensile strength and tear strength of the product.


The PVC auxiliaries contain specific anchoring groups which can be strongly anchored to the surface of the pigments and fully dispersed in the PVC system. The special dispersing segments of the PVC auxiliaries can make the polar components of the PVC multiphase system medium. Sex components, weakly polar components, non-polar components, and hydrophilic components are fully fused to eliminate problems such as phase-to-phase incompatibility or poor compatibility of microphase interphase microcracks caused by heterogeneous systems in PVC systems. Inorganic/organic hybrid composite obtained by in-situ polymerization of special monomers, which utilizes the "ball" effect of nano-particles and the dispersibility and compatibility of surface organic polymers to achieve PVC plasticization, improve melt flow, and improve surface. Gloss, giving PVC products better impact toughness and higher strength.
