Uses
Widely used in rubber, plastic, wire and cable, coatings, inks, paints, insulation materials, composite materials, building materials and other industries.。

Functions
Used in the rubber industry to improve dispersion properties and product release properties, surface finish and increased tortuosity products, also to improve the processing performance and mechanical properties of products. 


In the plastics industry to improve the use of plastic products, flexibility, strength and stability, but also to improve the processing performance of products, a substantial increase in the amount of padding to reduce mold wear, surface-treated calcium carbonate and filled in plastic and rubber pull tensile strength and impact strength without surface treatment was significantly higher than the calcium carbonate filler system, and shorten the kneading time in the process, improve production efficiency. 


In cable products can improve the electrical insulation properties, moderate acidity, good compatibility with resin, can increase the amount of padding to reduce costs, especially for filling in PVC wire and cable materials. 


Advanced ink, paint, paint, has better dispersion, stability, and can increase the glossiness, transparency, quick-drying and so on.
