Карбонат кальция KD8

⊙ Product features:

KD8 product is a product obtained by using ordinary calcium carbonate superfine powder as raw material, adding coupling dispersant for surface treatment, and surface treatment by surface modification equipment. Its PVC has good dispersion and low oil absorption.

⊙ Application field:

It is used in PVC sheet, PVC foam, PVC wire and cable, profiled material and other industries.

⊙ Main functions:

This product is made of calcium carbonate through modification, which reduces the agglomeration of calcium carbonate fine powder, improves the fluidity and dispersion of the powder. In the field of PVC processing, it has good compatibility with PVC and its processing aids. In the process of PVC foam extrusion, it reduces the consumption of lubrication in the later stage of processing, and ensures the sufficiency and stability of PVC foam. In the extrusion process of PVC wires and cables and profiled profiles, because of its good compatibility with PVC and processing aids, it can make PVC plasticizing effect better, surface gloss higher, and reduce the extrusion friction heat of the screw, reducing production energy consumption.
