RCF Ceramic Fiber Blanket

Standard blanket/High purity blanket/Synthetic high purity blanket/High alumina blanket/Zirconium blanket/Chrome blanket

Classification temperature:

Standard blanket:1260℃	High purity blanket:1260℃	Synthetic high purity blanket:1260℃
High alumina blanket:1400℃	Zirconium blanket:1430℃	Chrome blanket:1500℃

Thermal shock resistance
Low heat storage
Excellent sound absorption effect
Excellent heat insulation performance
Superior thermal stability, excellent resistance to powdering
Not affected by most chemicals (except Fluoride acid, phosphoric acid and strong base)
In some application environment, chrome blankets can be used at temperature above its classification temperature(5%contraction at 1500℃).
Using two-sided needling and thread throwing long fiber to produce tenacious, high resilience and high strength fiber blankets with resistance to tearing before and after heating

ANGKARL ceramic fiber blankets are spread ones with continuous falling cotton, which have higher tensile strength and flat surface after double-sided needling process. There is no organic binder.
·It owns excellent resistance to chemical erosion (except hydrofluoric acid, phosphoric acid and strong base, such as Na₂0,K₂O)
·Its performance is not affected by oil and water. Its thermal and physical properties can be restored after drying.
All materials of blankets can be treated to make them waterproof

Furnace lining, boiler heat insulation, control of heat treatment temperature
Heat insulation of glass kiln top, furnace door sealing, flue lining
Heat insulation of pipe, heat insulation components of transport and communication facilities
Fireproofing and heat sealing gaskets for household appliances
Thermal stress release and heat insulation in hot weld of outdoor welding
High temperature filter medium
Nuclear heat insulation
Insulation of steam and gas engines
Thermal resistance elements for automotive industry Site weld
