The product is a new high-performance and multi-function granular organic silicon plastic lubricant. As a dispersing lubrication modifier, the product adopts a special modified organo-silicon polymer as the major component and uses a few functional auxiliaries. The product is suitable to be matched with granular resins or granular fillers to produce plastic products through direct extrusion or injection moulding. The organic silicon plastic modifier is able to improve the processing conditions of various thermoplastics and improve the performance of plastic products. It can improve the fluidity of fusion resin, reduce the energy consumption of injection and extrusion processing, extend the service life of the processing equipment, improve the surface smoothness of plastic products and improve the strength and resistance to wear of the products.
