Performance
Widely applied in Industries such as rubber, plastics, papermaking, paint, building toothpaste etc.
Rubber industry: Calcium carbonate is the earliest filler used in rubber industry. It can increase the volume for saving cost. It also can improve the processing performance and the vulcanizing properties.
Plastic industry: improve the stability of plastic product size, improve the plastic processing performance and product heat resistance.
Papermaking: As paper filler, it not only reduce the pulp for saving cost, and helps in sizing of paper at neutral and alkaline PH.
