Temperature degree: 1260℃ (2300℉)
CCEWOOL® Research series intumescent ceramic fiber paper is produced from a mixture of high purity ceramic fiber, natural graphite fine flakes, and organic binders through a fiber washing process. At about 1200 ℉ (649 ℃), the paper expands up to maximum of 400% of its thickness. This feature serves as excellent material for gasket and sealing applications.
Strict control of raw materials
Control impurity content, ensure low thermal shrinkage, and improve heat resistance
1. Self owned raw material base, all material will be fully burnt by rotary kiln to reduce the impurities content such as CaO.
2. Strict material inspection before entering factory, special warehouse to guarantee the purity of raw material.
3. Computer-controlled ingredient proportion provides consistent material proper ties.
4. Through strict control at each step, we reduce the impurity content of the raw materials to less than 1%. The CCEWOOL expandable ceramic fiber papers are pure white, and the linear shrinkage rate is lower than 2% at the hot surface temperature of 1200°C. The quality is more stable, and the service life is longer.
Production process control
Reduce the content of slag balls, ensure low thermal conductivity, and improve thermal insulation performance
1. The ordinary ceramic fiber paper doesn’t expand when heated, but the expandable ceramic fiber paper will expand when heated thus offers its better sealing effect. Manufactured through 9 shot-removal process thus shot content is 5% lower than similar products.
2. The fully automatic ceramic fiber paper production line has a full-automatic drying system, which makes the drying quicker, more thorough, and more even. Products have good dryness and quality with a tensile strength higher than 0.4MPa and high tear resistance, flexibility, and thermal shock resistance.
3. The temperature grade of CCEWOOL ceramic fiber paper is 1260 oC-1430 oC, and a variety of standard, high-aluminum, zirconium-containing ceramic fiber paper can be produced for different temperatures. CCEWOOL has also developed CCEWOOL ceramic fiber flame-retardant paper and expanded ceramic fiber paper to meet the needs of customers.
4. The minimum thickness of CCEWOOL ceramic fiber paper can be 0.5mm, and the paper can be customized to a minimum width of 50mm, 100mm and other different widths. Special-shaped ceramic fiber paper parts and gaskets of various sizes and shapes can be customized, too.
