PVC Stabilizer&Plastics Processing
Wax for PVC profile has low viscosity, high softening point, good hardness, non-toxicity, good thermal stability, low high-temperature volatility and other performance. As a lubricant, it has stable chemical properties and good electrical properties.
※Increase the extrusion efficiency of PVC products, improve the surface gloss of PVC products, and can effectively enhance the plasticization degree of PVC products processing system.
※Increase the gloss of the surface of products and have excellent dispersibility to pigments. As an additive, it can be directly added to polyolefin processing, which can increase the gloss of the products.
※Greatly improve the processing performance, the fluidity in the process and the extrusion efficiency of products.
※Improve the defects on the surface of the products, eliminate the melt rupture during plastic processing, reduce the irregularity of the film surface and blooming caused by excessive pressure.

The important application of PE wax lies in PVC processing. Compared with fatty acid lubricants, it has no adverse effects on melt tension and Vicat softening point, and provides excellent anti-adhesion and flow control. PE wax can be used to control melting in a special process. Even if the amount of addition is large, it has a very good compatibility with other components. PE wax is the only one of the known plastic lubricants that possesses both internal and external lubrications (demolding effect), and meanwhile keeps high transparency and having little effect on gelling. In addition, the low volatility of PE wax is very important for rolling and vacuum degassing. PE wax, as an internal lubricant, has good compatibility with polymer. It can reduce the cohesion of polymer molecules inside the polymer, thus improving the heat generation and fluidity of plastic melt. The function of PE wax as external lubricant is to improve the friction between polymer melt and hot metal surface of processing equipment. Due to its poor compatibility with polymers, it is easy to migrate from the melt inside to outside and therefore form a thin lubricating layer on the interface between plastic melt and metal.
This series of polyethylene wax products can effectively improve the fluidity of PVC heat stabilizer processing, increase the extrusion efficiency of PVC products, and improve the surface gloss of products. They can also effectively control the agglomeration of PVC heat stabilizer processing and effectively solve the precipitation of PVC heat stabilizer processing.
