Ceramic Chopped Fiber

1. Own raw material base; professional mining equipment; and stricter selection of raw materials.

2. The selected raw materials are placed into a rotary kiln to be fully calcined on site, which reduces the content of impurities and improves the purity.

3. The incoming raw materials are tested first, and then the qualified raw materials are stored in a designated warehouse to ensure their purity.

4. Controlling the content of impurities is an important step to ensure the heat resistance of ceramic fibers. High impurity content can cause the coarsening of crystal grains and the increase of linear shrinkage, which is the key reason for the deterioration of fiber performance and the reduction of its service life.

5. Through strict control at every step, we reduced the impurity content of raw materials to less than 1%. The CCEWOOL Ceramic Bulk Fiber is pure white, and its heat shrinkage rate is lower than 2% at high temperatures. It has stable quality and a longer service life.
