- DJM Insulating brick
Mullite insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM insulating brick is the new energy saving material for insulation.
- Ultrathin 6mm Ceramic fibre blanket
CCEWOOL Untral-thin Ceramic Fibre Blanket is a new type of fire-resistant insulation materials in white and tidy size, with integrated fire resistance, heat separation and thermal insulation functions, containing no any binding agent. All CCEWOOL Ceramic Fibre Ultra-thin Blankets are made though spun fiber production, which is widely used in various sectors of refractory, insulation, thermal insulation field.
- Ceramic Fiber Cloth
CCEWOOL Ceramic Fiber Cloth is a woven fabric made from our high quality ceramic fiber yarn. It is strong, lightweight, flexible, and available in a wide variety of thicknesses, widths and densities. Ceramic cloth contain absolute amount of binder material which is normally burned at lower temperature and does not affect the insulation property.
- Ceramic fiber paper
The product shows excellent thermal insulation properties and construction performance, suitable for use in deep processing (multi-layer composite, punching, etc.); and excellent resistance to molten infiltration, allowing itself to be used for casting washer separation in the construction and glass industries.
- Ceramic Fiber Modules
CCEWOOL Ceramic Fiber Modules is made from the corresponding ceramic fiber material acupuncture blanket processed in dedicated machines according to fiber component structure and size.
- Ceramic fiber board for wall-hung boilers and gas boiler
The most outstanding characteristic of CCEWOOL Ceramic fiber board for fireplace and gas boiler is that it enjoys light weight, and at the same time it has high compressive strength./ Compared with the normal ceramic fiber boards of the same density, they are 20% harder; comparing to the ceramic boards of the same compressive strength, they are 20% lighter.
- Ceramic Fiber Tape
Ceramic Fiber Tapes that are fabricated using high quality ceramic fiber yarn and are reinforced with fiberglass filament & ss wire.
- Ceramic fiber blanket
CCEWOOL Ceramic Fiber Blanket is a new type of fire-resistant insulation materials in white and tidy size, with integrated fire resistance, heat separation and thermal insulation functions, containing no any binding agent. All CCEWOOL Ceramic Fiber Blankets are made though spun fiber production, the working temperature is from 1050°C to 1450°C, which is widely used in various sectors of refractory, insulation, thermal insulation field.

The misunderstanding in the density of ceramic fiber insulation
The main composition of ceramic fiber insulation products is Al2O3 and SiO2, its heat capacity is basically same as refractory bricks. Ceramic fiber products formed empty pine unit structure because of fibers’ interlacement. So its bulk density greatly decreases and thermal conductivity is changed.
The thermal conductivity of 150%-250kg/m3 density ceramic fiber insulation products equal to 20% of 2070kg/m3 density refractory bricks. About 37%-40% of 1300kg/m3 density lightweight brick.
With the increase in density, the bulk density of ceramic fiber insulation products in the range of 150 ~ 250kg/m3 density, its’ the thermal conductivity heat loss gradually reduced. But with the increase in bulk density, its body structure and properties empty pine units also decreased. When then density more than 400kg / m3, its’ the thermal conductivity heat loss gradually increased, the comprehensive energy-saving also decreased.
