Features
1.Excellent resistance to chemical attack
2.Unaffected by oil and water
3.Thermal and physical properties restored after drying
4.High tensile strength
5.Light weight insulation,low heat storage,low thermal conductivity,thermal shock resistance
6.Install quickly and reliably over coated shells with or without vapor barrier
7.Better resistance to mechanical abuse than conventional blanket systems
8.The module is compressed by a certain amount in production.when it is used,the module expands and leaves no gap.this help to improve heat insulation.
Application
1.All furnace linings requiring protective barrier against shell
2.Process heaters
3.Heat treating furnace
4.Forge furnace
5.Incinerators
