Lightweight Mullite Insulation Brick For Industrial Furnace High-Temperature Refractory
Leadsun supplies several grades of insulating bricks for applications ranging from 1260°C to 1760°C. Each grade is designed to meet specific thermal and physical requirements, and every brick is precisely machined to tight dimensional tolerances after firing.
These insulating bricks are manufactured from high-purity clays and selected ceramic materials. Carefully graded organic materials burn out during firing, creating a uniform pore structure that ensures excellent insulation performance.
