PVC external lubricant is a high-efficiency external lubricant specially developed for rigid polyvinyl chloride (PVC) processing. Manufactured using a complex ester synthesis process based on multifunctional fatty acids, it exhibits excellent metal release properties and long-lasting lubricating performance. It is a mainstream lubricant additive for rigid PVC pipes, profiles, fittings, and highly filled products.

In terms of performance characteristics, this product significantly extends the material's plastication time while effectively reducing equilibrium torque and processing temperature. It greatly enhances the free-flowing properties of the compound, completely eliminating sticking to the processing equipment (such as the calender rolls or extruder barrel) during operation. This not only facilitates easier equipment cleaning but also ensures a smooth surface finish and pure color of the final products. Furthermore, this product exhibits excellent transparency and mold release properties in the processing of transparent PVC articles, notably improving melt fluidity and enhancing anti-adhesion performance.

PVC external lubricant is primarily suitable for the processing of transparent sheets, pellets, shrink films, twist films, calendered films, and various other opaque PVC products. As an internal and external release agent, it also performs excellently in fields such as polyurethane plastics. With its stable and reliable quality and high cost-effectiveness, it provides PVC processing enterprises with a superior lubrication solution, effectively improving production efficiency and product quality.

The product is packaged in 25 kg woven bags with sealed closure, has a shelf life of two years, and should be stored in a dry place away from light and moisture. Its lubricating effect is lasting and stable, helping to reduce equipment wear and decrease the frequency of shutdowns for cleaning, while balancing production efficiency and finished product quality. It stands out as a cost-effective external lubricant option for rigid PVC processing.
