Ceramic fiber vacuum formed shapes (MWOOL – SHAPED) are made of high-purity ceramic fibers with a small amount of binders through vacuum forming. There are several grades including 1000℃, 1260℃, 1400℃, 1500℃, 1600℃, 1700℃, and 1800℃. Ceramic fiber vacuum formed shapes can still maintain good mechanical strength in a hot state.
MWOOL – SHAPED Characteristics:
• Uniform density and thickness;
• Low thermal conductivity, shrinkage and heat capacity;
• Good high temperature stability;
• Direct contact with flame and excellent thermal shock resistance;
• Good rigidity and flexural strength and self-supporting;
• Excellent resistance to airflow erosion;
• Chemically stable and resistant to most aggressive chemicals (except phosphoric acid, hydrofluoric acid and strong alkalis);
• Easy to cut or machine processing and can be made into multiple complex shapes.
Typical Application:
MWOOL – SHAPED can be used for burner brick, observation hole and manhole, electrical component carrier, riser sleeve, nozzle and tundish, roll seal, catalytic converter insulation, pipe insulation, and electric heating device carrier, etc.
In the electric heating furnace, vacuum forming technology and high-quality electric heating elements can be used to make an electric heating device integrated with “heating and insulation”. This can solve the problem of combining ceramic fibers with electric heating elements.
According to customer requirements, it can be made into flat, curved, semi circular, tubular, and small furnaces.
