Detailed introduction

Surface treated calcium carbonate (active type)


Compared with pure calcium carbonate, it has the following advantages: narrow particle size distribution range, reduced water absorption, reduced oil absorption value, and good affinity with resin


It can improve the tensile, compressive and wear-resisting properties of the products, shorten the melting time after mixing, reduce the balance torque, high dispersion, easy coloring and increase the gloss of the surface of the products.


Usage: in the rubber industry can improve the dispersion and demoulding performance of products, increase the surface finish and bend properties of products, but also improve the processing performance and physical and mechanical properties of products.


In the plastic industry can improve the flexibility, strength and stability of plastic products, but also improve the processing performance of products, greatly increase the amount of filling, reduce the wear of abrasive tools. The tensile strength and impact strength of surface treated calcium carbonate filled plastic and rubber are obviously higher than that of untreated calcium carbonate filled system, and the kneading time is shortened in the process of processing, and the production efficiency is improved.


In cable products, can improve the electrical insulation performance. Moderate pH, good compatibility with resin, can increase the filling amount and reduce the cost, especially suitable for filling PVC wire and cable material.


In the advanced ink, paint, paint with better dispersion, stability, and can increase the gloss, transparency of products, etc.
