The chemical formula of silicon dioxide is SiO2, and XJ-KK-01 is made of LLDPE as the base material and silicon dioxide, and the composite additive is extruded by twin-screw and cut under water. The silica content is 35-50%. The product has opening, smooth and anti-bonding properties, mainly used in PE, PP, EVA, PVC film blowing, casting film processing and forming, and reduce the friction coefficient.
