■ Heating test result (entire surface)

DAIPALITE series composed of Xonotlite crystal keeps its shape up to 1000℃ though others are up to 650℃.

The reason is the difference of the crystal. Xonotlite crystal is strong against heat.

The heating linear shrinkage ratio after three hours of heating at 1000℃ is max 2.0%.

■ Heating test result (one side)

Normally said, other calcium silicate materials can be used up to 650℃.
However, many cracks occurs on the material when it is heated form only one side.

On the other hand, no cracks on DAIPALITE series composed of Xonotlite crystal.
The material can be used repeatedly.
