JIS heat Insulation brick with:
1.Lower content in iron, alkaline and impurities,
2.Good high temperature properties.
Application:JIS series heat insulation bricks (A and B series thermal insulation bricks) are produced accordance with Japanese industrial standard especially for export to Japan, Korea and East-south Asia countries. These products are widely used in cement kiln, heat stove and some other heating devices.
