Insulation grains Lightweight refractory grains with low thermal conductivity and good insulation performance result in significant energy savings. DirgodazAmol Company manufactures various types of insulation grains (SD-LA series) based on low alumina compositions with low iron oxide content. . These grains are generally available in different particle sizes of 1, 3-1, 5-3 and 5-8 mm.
Advantages and specifications:
SD-LA series products have higher thermal stability than lightweight materials such as perlite, vermiculite and some ceramic fibers, low thermal conductivity, good strength, high purity and low iron oxide content, resistance to corrosive environments and health-reducing environments. .
As a raw material in integrated refractories such as insulation refractory mass and prefabricated forms as a filler in the insulating layers and components of high temperature industrial furnaces and ceramic industry furnaces.
