Cermic fiber shapes are produced from corresponding level refractory fibre mixture through vaccum forming.
Cermic fiber shapes without burning is free shear and bending. They are the ideal energy-efficient insulation materials of a furnace, piping and other equipment Support Surface hardening or completely hardening to every level shapes according to customers' demand.
Applications:
1.Peep holes for the industrial furnace
2.Patch holes for thermometer
3.Nozzle and door sealing for the industrial furnace
4.Non-ferrous metal molten channel
5.Lining for pad,cap,of found,electrical equipment connect gaskets
Main Features:
Can be made into various of complex shapes, high dimension accuracy.
Contact with flame directly,no odor and volatile gases at high temperatures
High mechanical strength,resistance to gas flow.
Low shrinkage,low thermal conductivity.
Excellent strength in high temperature and thermal stability.
