  • HCT-121 Special level Aluminium hydroxide
  • Product Introduction

    Special aluminum hydroxide production process, using pure sintering product aluminium hydroxide iron content is extremely low, high whiteness, known as "China white" by the Chinese and foreign users. The aluminum hydroxide has unique optical properties (refractive index of 1.57), it can be used as solid surface material production (artificial marble) with the polyester resin or dilute acid resin filler, the basic materials of toothpaste, etc. In order to adapt to the different requirements of different USES, equipped with standard size to fine particle and other various types of products. Currently has high dry white, white, three major series ultrafine ten a variety of special aluminium hydroxide product specifications.
