Introduction
WH Non-asbestos calcium silicate insulation products are Xonotlite type natural gas hydrates by thermoplastic reaction and mixture inorganic fiber made into high-property insulation materials. Products highest use temperature for 1000ºC, and Can provide water repellent products according to customer needs.
Characteristics
Low thermal conductivity, excellent insulation
Low thermal shrinkage, good thermal stability
Good durability can bear high temperature continuous heat load
Light weight, high specific strength
Resistance to high temperature, Non-deformation at operating temperatures
Waterproof, no change the property after drying
Easy to install, Good mach inability
excluding asbestos
