The Characteristics and Index of Barium Sulfate for Engineering Plastics
2015/07/12 Bmschem
The barium sulfate for engineering plastics, which is made by high-tech nanotechnology, has characteristics of small particle size, narrow distribution, good chemical stability, good dispersion and high whiteness. It can be widely used in all kinds of engineering plastic products. This barium sulfate can significantly improve product surface gloss, tensile strength, thermal conductivity, wear resistance, weather resistance and significantly reduce molding shrinkage, friction coefficient and cost. It significantly reduces molding shrinkage of plastic products and improves stiffness and hardness.
Product Features:
1 It has high L value and good dispersity. The product surface has high gloss and colour brightness.
2 It has acid resistance, alkali resistance, high temperature resistance, good thermal conductivity and weatherability
3 It has good dispersity and its deflocculation on pigment can reduce the dosage of color masterbatch.
4 It has small particle size. Surface modification can effectively improve its various mechanical properties.
5 It has X ray development and can be used in medicine and all kinds of children's products.
6 The friction coefficient of products can be reduced, and the solvent resistance is good.
7 It has small particle size, low scattering rate, high color rendering and transparency.
8 It has less impurity, less black spot, no harmful substance and ensures the safety and cleanliness of products.
