CCEWOOL® HD Calcium Silicate Board

CCEWOOL High-Density Calcium Silicate Board is a specialized refractory board developed for the non-ferrous metal industry, with a density up to 1000kg/m3, compressibility up to 20Mpa, making it highly suitable for high-temperature areas that need to withstand certain pressures. And it has an exceptionally long service life. CCEWOOL High-Density Calcium Silicate Board comes in two types: glass fiber-reinforced and carbon fiber-reinforced, and can be custom-made into various shapes according to customers’ drawings.

CCEWOOL® High-Density Calcium Silicate Board is characterized by its high resistance to metal melts wetting, especially non-ferrous metal melt and glass melt. It finds wide application in demanding environments that requires high temperature resistance, high thermal shock resistance, and high corrosion resistance.

CCEWOOL® High-Density Calcium Silicate Board boasts low thermal conductivity, excellent thermal stability, high resistance to infiltration and corrosion, as well as outstanding machining properties. It can be used to manufacture various components for the non-ferrous metal industry, including but not limited to: crucibles, runners, hot top rings, brake pins, lugs, floaters, continuous casting nozzles, cushion plates, in-groove storage for flow channels, machined vertical pipes, front boxes, and molds for the glass industry, as well as grates for the aluminum industry, aluminum melt spouts, pour spout liners, and aluminum industry transition plates.

CCEWOOL® High-Density Calcium Silicate Board can directly contact aluminum melt, and aluminum melt does not adhere to it, offering a lifespan five times longer than ordinary materials. It can withstand temperatures of up to 1000°C (1832°F).


  • Precision-Cut for Easy Installation

    Accurate sizes, polished on both sides, and cut on all sides for safe and convenient installation.

  • Lightweight and Easy to Install

    Small volume density, the lightest among hard insulation materials, requiring thinner insulation layers, less rigid support, and low installation labor intensity.

  • Durable and Long-Lasting

    CCEWOOL calcium silicate boards can be reused for decades without compromising technical performance.

  • High-Strength and Durable Insulation

    High strength, no deformation within the operational temperature range, asbestos-free, durable, water and humidity proof, ideal for heat preservation and insulation of various high-temperature parts.
