Fireproof plastic for sale

Fireproof plastic is made from pure raw materials with low iron and impurity content through reasonable sorting and high-efficiency additive. It has high fire resistance, good abrasion resistance, high resistance to thermal shock, high corrosion resistance and other excellent characteristics. It can be divided into different materials depending on the raw materials used.
