product details

• DESCRIPTION

Ceramic fiber chopped strand(chopped fiber) is a kind of short fiber form material obtained by mechanically cutting ceramic fiber blankets or loose cotton. It is widely used in refractory, sealing, coating and composite materials, and is an important "secondary processing raw material" in the ceramic fiber system.


• PROPERTIES

Ø Light weight, high strength. 

Ø High oxidation resistance.

Ø Low thermal conductivity.

Ø Good softness.

Ø Good corrosion resistance.

Ø Good Reinforcement Performance and Sound Absorption Performance.


• APPLICATION

Ø Flexible thermal insulation materials for high temperature pipes of industrial furnaces, boiler linings and backing. 

Ø Refractory castables and gunning materials.

Ø High-temperature insulation coatings.

Ø Expansion joints and sealing materials. 

Ø Fireproof boards and composite panels. 

Ø Automotive and industrial heat shielding.


• SELECT DEPENDS ON USAGE

ØFor coatings or catalysts:
Choose length < 1 mm with good dispersion

ØFor composite reinforcement:
Choose length > 3 mm with low shot content

ØFor further processing (blankets, paper):
Choose 6–12 mm fibers with suitable temperature ratings
