PVC Processing Aid
IntroductionPVC Processing aid is a kind of polymer additive, adding a small amount of time, can improve the melting processing performance of thermoplastic.As a result of hard PVC processing temperature and decomposition temperature is close to, difficult to form, and melt viscosity is larger, poor fluidity, resin adhesion is not high, easy to produce melt rupture, so that the appearance of products become poor, the use of processing additives, can be very good to overcome these defects and problems.Action principleAfter PVC Processing aid is added to THE PVC system, the hard PVC processed in solid state, viscoelastic state and thermoplastic state has the wall adhesion performance, and the melt is transformed into the wall adhesion melt with shear flow, which improves the thermal stress of the melt, accelerates the plasticization process of the system, improves the plasticization status, and also significantly improves the quality of hard PVC products and semi-finished products.PVC Processing aid and PVC have good compatibility. PVC Processing aid can be integrated into THE PVC matrix to transmit shear stress and promote the fracture of multiple PVC structures to achieve uniform plasticization.High relative molecular weight PVC Processing aid can effectively improve the melt strength and elongation of PVC matrix and improve the mechanical properties of products by winding with relatively short and rigid PVC chains.In addition, external lubricating processing agent PVC Processing aid molecular chain and PVC incompatible part can play a lubrication role, in the molten state, this part of the chain segment will migrate to the surface of the system, improve the hot metal stripping of materials, improve the release.Why choose us ?1.
