Product Details

high density Calcium Silicate Board for thermal insulation

Product Description

High density calcium silicate insulation board is developed for nonferrous metal industry with density range 800-1000KGS/M3, used for conveying, casting and molding of molten alumina and other non-ferrous metals, also can be used as clamping fixture in glass industry. Besides its own thermal insulation, its non-stick aluminum characteristics have been greatly played. High strength, good machinability, can be used to machine precision products and complex parts by Numerical Control Machine Tools.

There are two types of board reinforced by glass fiber and carbon fiber.

Features and advantage

1. Low thermal conductivity and less heat lost in high temperature

2. Not wetted by molten alumina

3. Resistance to thermal shock

4. Excellent machining performance

5. Asbestos-free

Application

1. Ladle insulating panels

2. Clamping fixture for car glass

3. Dip tubes

4. Pouring spouts

5. Hot-top rings

6. Stopper pins

7. Rolling edge

8. Floats

9. Launders
