Application fields:
1. Rubber: a large amount of filling in rubber products can increase the volume of products, so as to save expensive natural rubber or synthetic rubber and achieve the purpose of reducing costs; The processing property was improved, and the vulcanization system was not affected by the addition ratio; Improve the properties of vulcanizate, play a reinforcing or semi reinforcing role; The hardness can be adjusted by changing the filling amount; Adjust viscosity in latex glue and rubber glue.
2. Plastic: in the plastic can play a skeleton role, improve the dimensional stability of plastic products; Improve the hardness and rigidity of plastic products; It can change the rheological properties of plastics; Improve the surface gloss and smoothness of products; Reducing the shrinkage, coefficient of linear expansion and creep properties of plastic products is helpful to the processing and forming of plastics; Improve the heat resistance and astigmatism of plastic products; Reduce the cost of plastic products.
3. Papermaking: adding in the paper can ensure the strength and whiteness of the paper, reduce the cost, and is superior to talc in whiteness, opacity and fineness; The white pigment used as coating in coated paper has the advantages of high whiteness, adjustable ink absorption, better covering power and optical properties.
4. Coatings: Fillers widely used in coatings, play a role of skeleton. Filling in oil-based coatings can thicken and thicken the coatings, and play a role of filling and leveling. It is an ideal matting filler in topcoat;
