Kaolin

---

■ Brief Introduction

Rubber specific kaolin is a fine powder of aluminum silicate produced by controlling different calcination temperatures and dehydrating coal bearing kaolin. This kaolin has a low density, Good dispersion performance, high volume fraction after mixing, can play a role in strengthening,increasing capacity, and reducing costs.

■ Product Features

• Improve the mechanical properties of rubber products, such as tensile strength, modulus at break, elongation at break, etc

• Improve the insulation and insulation retention of products

• Has the function of strengthening and increasing capacity

• Can adjust hardness and improve processing performance such as mixing, extrusion, and molding

• Improve dispersion and mechanical strength of products
