1250Ultra-fine calcined kaolin, coating kaolin, rubber kaolin, and kaolin for cable materials.

Here's the translation: **Yuanjiang Brand** - 1250 Ultra-fine calcined kaolin is an important industrial non-metallic mineral, scientifically known as hydrated aluminum silicate (aluminosilicate clay mineral). The chemical composition is Al2O3 2SiO2 2H2O It is a light gray, fine flaky powder with a triclinic crystal system and a quasi-hexagonal configuration. The specific gravity is 2.8 , with a hardness of Mohs 1.0 The refractive index is 1.56 It is a slightly acidic mineral, yet it still possesses good acid and alkali resistance. In addition to the general characteristics of mineral powders, it has a significant blocking effect on infrared radiation. However, it is prone to moisture absorption and should be dried before use. The calcined kaolin products manufactured by our company feature high whiteness, strong covering and hiding power, bright gloss, fine particle size, fast adsorption speed, excellent acid and alkali resistance, moderate oil absorption, and stable physicochemical properties. It is a new type of plastic additive widely used in papermaking, coatings, and inorganic pigments.materials, cables Industries such as ceramics, pharmaceuticals, organic polymer industry, grinding wheels, and building materials.
