Refractory Plastic Manufacturer

Refractory plastic is made of pure raw materials with low iron and low impurity content through reasonable grading and high-efficiency admixture. It has high fire resistance, good abrasion resistance, strong thermal shock resistance, strong corrosion resistance, and other excellent characteristics. It can be divided into different materials according to the raw materials used.
