For PVC pipes (such as drainage pipes, electrical conduits, wiring ducts and non-drinking water supply pipes), it can effectively inhibit PVC decomposition during high-temperature extrusion processing, avoid yellowing, scorching and material deterioration. It also has good internal and external lubrication, ensuring smooth pipe surface, stable dimensions and consistent batch quality. Provided in flake form to reduce dust pollution, it features excellent electrical insulation properties and high cost performance.
