Product Description

Polycrystalline fiber bulk has low density, low thermal conductivity, good thermal shock resistance, high working temp, good chemical stability, good anti-corrosion etc features, it is widely used in metallurgy, construction, ceramics, aerospace, military etc industries.

PCW blanket is made by PCW fiber, double side needled, contains no binder or other additives. Under oxidation atmosphere, neutral atmosphere, and weak reducing atmosphere, PCW blanket still keeps good strength, softness and fiber structure.

PCW blanket has better acid-alkaline erosion resistance than alumina silicate fiber. PCW blanket thermal insulation effect is very excellent because it contain no any shot.

Typical Features of PCW blanket

Low thermal conductivity
Low shrinkage under high temp
Excellent thermal shock resistance
Ideal module feeding material, good softness under high temp
Low heat capacity
Good sound absorption
High strength, easy processing, no tears and holes around anchor area.
Good chemical stability and erosion resistance.

Typical Application

PCW fiber: PCW blanket, felt, board, VF shapes etc feeding, furnace lining above 1400℃; sealing in high temp furnace expansion joints; piston, brake pad etc strengthening materials; insulation material in rocket motor or other aerospace, military insulation material; Vehicle Catalytic Converter gasket material in European Ⅲ and above exhaust emission standards.

PCW blanket: Hihg Temp furnace lining, ceramics fast firing furnace, petrochemical furnace, high temp sealing gasket, furnace door sealing, high temp filter media.

Typical Features of PCW Bulk

Low thermal conductivity, low heat capacity
Excellent chemical stability
Excellent thermal stability
Containing no binder and erosion materials
Good softness and tensile strength under high temp
