Adding B564 to the formula of polyvinyl chloride will significantly improve the toughness of the product, but it will not have any adverse effects on the inherent properties of polyvinyl chloride, such as thermal stability and processability. B564 comes in powder form and is suitable for dry blending with PVC. Its mixture can be made into various rigid, semi-rigid and soft products such as pellets, films, sheets, plates, profiles, pipes and bottles through blow molding, calendering, extrusion and injection molding. B-564 focuses on improving the ultra-high impact strength and toughness of opaque PVC pipes (especially water supply pipes), PVC pipe fittings (especially water supply pipe fittings), and PVC profiles. B-564 has good dispersibility for injection molding processing in higher temperature, low shear area. In particular, the impact strength in the area of ​​ductile failure is greatly improved. Especially suitable for opaque injection-molded pipe joints, wire boxes, etc.
