Imported plastic modifier GFS-8 is a non-toxic processing aid ideal for polyolefin plastics such as SBS and PVC. It can lower material temperature and melt viscosity during processing; significantly reduce or eliminate shear stress during plastic processing, lower equilibrium torque, promote plasticizing properties, and enhance fluidity and output capacity. This can increase extruder output by 5-10%, thereby improving efficiency and reducing power consumption. GFS-8 improves the finish of finished products, making them smoother and denser, and enhances mold filling, significantly enhancing the surface properties of finished products. GFS-8's high fluidity makes it particularly suitable for use in highly filled formulations, creating a synergistic effect with fillers while significantly reducing costs.
