The product with fine particle size, narrow distribution of particle size, high whiteness and low impurity. It has great malleability and reinforcing performance for rubber and pigment. After filling, rubber has good tinting strength and high opacity. It is an excellent white reinforced filler, and can partly replace white carbon black. The product can be used to enhance color and coating strength.
Main application:
Cable, rubber, sealants, etc.
