China High Density Calcium Silicate Board Specification

High Density Calcium Silicate Board Specification
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 nonstick 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.
