 Feb 18, 2024|View:130

Brief introduction:

Pigment grade high purity zinc sulfide S-20 is a new product model produced by Yunfu Hongzhi New Materials Co., Ltd. by using new technology. It is a soft multi-functional white pigment with 2.37 refractive index, excellent temperature resistance, high thermal conductivity, low Mohs hardness and good dispersion.

Compared with ours pigment grade zinc sulfide S-10, high purity S-20 has higher purity and better temperature resistance. It is used in PTFE, PPO, PSU, PEEK, PI, PPS, LCP and other special engineering plastics to better play the high temperature resistance, corrosion resistance, wear resistance, high strength and other properties of special plastics, and extend the service life of products.
