Bio Soluble Fiber Blanket
Bio Soluble Fiber Blanket
Bio Soluble fiber blanket is a body soluble fiber that utilises a unique spinning technology to create a special fiber with superior thermal and mechanical properties. This special fiber is made from a blend of calcium, silica and magnesium which give fiber the ability to support continuous temperatures up to 1260C.
Ceramic Fiber Cloth
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.
Ultrathin 6mm Ceramic fibre blanket
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 board for wall-hung boilers and gas boiler
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 Modules
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 paper
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 Tape
Ceramic Fiber Tape
Ceramic Fiber Tapes that are fabricated using high quality ceramic fiber yarn and are reinforced with fiberglass filament & ss wire.
DJM Insulating brick
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.

From the technical point of view, the difference between CCEWOOL ceramic fiber spun bulk and blown fiber as follows:

     1. Diameter: spun fiber more thick, diameter is generally 3.0-5.0μm, blown fiber is generally 2.0-4.0μm;

     2. Length: spun fiber is longer than blown fiber generally 150-250mm, blown fiber is generally 100-200mm;

     3. Thermal conductivity: ceramic fiber spun fiber’s thermal conductivity better than blown fiber because  it is very thin;

     4. Tensile flexural strength: ceramic fiber spun bulk better than blown fiber because it is more thick.

Two different applications of 2 types CCEWOOL ceramic fiber:

     1. Making CCEWOOL ceramic fiber module: ceramic fiber spun bulk is thicker and longer blown fiber. In the process of making folding block, blown fiber blankets easily break and tear while spun fiber blanket can be folded very tight and difficult to damage, the quality of the block will directly affect the quality of the furnace lining;

     2. Large blanket’s vertical layer application in boiler insulation : ceramic fiber spun bulk with better pull resistance, more durable, better than blown fiber blanket;

     3. The application in ceramic fiber textiles: spun bulk is coarse and long and having excellent spinning property. So ceramic fiber spun bulk is special raw materials for ceramic fiber textile (cloth, tape, rope, yarn, etc.) 

     4. CCEWOOL ceramic fiber board application: ceramic fiber blown fiber is short and thin, in low thermal conductivity and more suitable for decentralized fragmentation. It can be the raw material of ceramic fiber paper and ceramic fiber board.

     CCEWOOL ceramic fiber spun bulk has self owned raw material base, all material will be fully burnt by rotary kiln to reduce impurities content such as CaO. All CCEWOOL ceramic fiber bulk’s shot content is 5% lower than others’ products with characteristic of pure white and stable quality.
