$Refractory Plastics$

Refractory Plastics

Wear-resistant refractory plastics have the advantages of convenient construction, good plasticity, and good wear resistance. The wear-resistant layer after construction features very high strength and wear resistance.

$Refractory Castables$

Refractory Castables

Low and ultra-low cement castables feature small pore size, high density, good volume stability, high strength, and low water addition. They overcome the characteristic of significant strength reduction of ordinary castables at 800~1200℃; instead, their strength increases with rising temperature.

Acid-Resistant Bricks

Acid-resistant bricks possess excellent corrosion resistance to organic and inorganic acids (excluding hydrofluoric acid), along with good strength and wear resistance. They are widely used in acidic atmosphere flues, autoclaves and recovery boilers in the acid pulping industry, as well as large acid-resistant pool containers and storage tanks.
