Product introductionWhite powder.

 

Introduction: Strengthening and toughening, with fine, uniform, high whiteness, optical properties and other advantages.

 

1. Rubber industry: After surface modification, nano - calcium carbonate has good compatibility with rubber, It has the properties of reinforcing, filling, toning, improving processing technology and products, Can make rubber easy to mix, easy to disperse, after mixing soft gum, rubber surface smooth; It can improve the ductility, tensile strength and tear strength of the products.

 

2. The plastics industry :Nano-calcium carbonate is characterized by high gloss, low wear rate, surface modification and oil repellency, can be filled in polyvinyl chloride, polypropylene and phenolic plastics and other polymers, widely used in plastic and PVC cable packing.

 

3. Coating industry: Can improve the adhesion of paint, wash resistance, stain resistance, improve the strength and surface finish,And it has a good anti-sedimentation effect.

 

4. Printing ink industry: Using nanometer calcium carbonate ink configuration, Viscosity is better,has good printing performance,  good stability, dry quickly and have no opposite effect.

 

Application:Widely used in a variety of coatings, plastics, rubber, paint, ink paper, ceramics, batteries, enamel, cosmetics and other fields.
