Product Description

Five special properties:
1. Stable properties
2. Expansion property is good as its Al2O3 comes from kyanite and swell capacity increases with increasing Al2O3 content
3. The lower swelling temperature, and with increasing temperature it has stable swelling curve and obvious tendency
4. Lower impurity such as K2O&Na2O, without topaz phase and mica phase
5. Be in light blue color and competitive price
