CCEWOOL ® research series water repellent ceramic fiber blanket is needled blanket with super high tensile strength which is made from spun ceramic fiber bulk. It is produced with unique inside double needle technology with solvent-based high-temperature nano-hydrophobic material as the surface treatment agent.
CCEWOOL ® research series water repellent ceramic fiber blanket is needled blanket with super high tensile strength which is made from spun ceramic fiber bulk. It is produced with unique inside double needle technology with solvent-based high-temperature nano-hydrophobic material as the surface treatment agent, and has the characteristics of excellent overall hydrophobicity which greatly improved the insulation performance of the fiber blanket and solved the problem of decreasing of thermal insulation performance and corrosion of insulated object caused by moisture absorption of conventional fiber blankets.

1. The fully automated batching system fully guarantees the stability of the raw material composition and improves the accuracy of raw material ratio.
2. With an imported high-speed centrifuge of which the speed reaches up to 11000r/min, the fiber forming rate becomes higher. The thickness of CCEWOOL ceramic fiber is uniform, and the content of slag ball is lower than 10%. The slag ball content is an important index that determines the thermal conductivity of fiber. The thermal conductivity of CCEWOOL ceramic fiber Water-repellent blanket is lower than 0.28w/m.k in a high-temp environment of 1000°C, so they have an excellent thermal insulation performance.
3. The condenser spreads cotton evenly to ensure the uniform density of CCEWOOL ceramic fiber Water-repellent blankets.
4. The use of the self-innovated double-sided inner- needle-flower punching process and the daily replacement of the needle punching panel ensure the even distribution of the needle punch pattern, which allows the tensile strength of CCEWOOL ceramic fiber Water-repellent blankets to exceed 70Kpa and the product quality to become more stable.
5. CCEWOOL ceramic fiber water-repellent blankets use solvent-based high-temp nano-hydrophobic material as the surface treatment agent, reaching a water-repellent rate of over 99%, which realizes the overall water-repellency of the ceramic fiber blankets and solves the issue of the decrease in thermal conductivity caused by moisture absorption of conventional fiber blankets.
