YP series calcium carbonate Features: It is a product obtained by using marble as raw material, adding coupling dispersant, etc. for surface treatment, and surface treatment through surface modification equipment. Its PVC application has good dispersion and low oil absorption. Application areas: PVC pipe, PVC foam, PVC wire and cable, profiled materials and other industries. main effect: This product is modified by calcium carbonate, which reduces the agglomeration of fine calcium carbonate powder and improves the fluidity and dispersibility of the powder. In the field of PVC processing, it has good compatibility with PVC and its processing aids. In the extrusion process of PVC pipes, because of its good compatibility with PVC and processing aids, it can make the PVC plasticization effect better, significantly improve the tensile strength and elongation at break, and at the same time, the surface gloss is higher. The toughness at the same time gives the pipe a yellowish-white color.
