Product Introduction
Product Details
LI®CA6THERMALINSOLATIGMATERAL is a kind of high temperature insulation refractory material, designed for heat loss requirements of strict insulation occasions, can be directly used as a work lining, taking into account the dual role of insulation and fire resistance, with comparable to the low thermal conductivity of refractory fiber.
Stereotype material lightweight refractory brick is divided into 0.4, 0.6, 0.8, 1.0, 1.2 five brands, long-term use temperature is 1400 ℃, 1400 ℃,1600 ℃,1600 ℃,1650 ℃. It can also be produced according to the volume density level required by users.

| Advantage Features | A thermal conductivity is the 1/3 of mullite and alumina hollow sphere materials with the same density and the same temperature even smaller. B thermal conductivity increases with temperature does not increase but decreases, that is, negative growth. Negative growth thermal conductivity is very favorable for high temperature insulation. C high temperature volume stability. D can replace JM26JM28JM30 and hollow alumina ball and other grades of insulation materials, and the insulation effect is better than these materials. E is an ideal high-temperature material resistant to CO and H2 chemical attack, and its corrosion resistance is Grade A. Because the free energy of the reaction of alumina material with CO and H2 is lower than that of CA6. |
