Import Calcium Silicate Board — Buy in Bulk from Supplier in China

Calcium silicate board from Hongyi Building Material Co., Ltd is a non-asbestos, rigid insulation material designed for high-temperature applications, with a safe use temperature ranging from 650 to 1000°C. The product is manufactured from silicon powder, calcium oxide, fiber-reinforced materials, and additives, processed through mixing, molding, steam curing, and drying to create a lightweight, porous structure. Its low thermal conductivity of 0.06 W/(m·K) and apparent density of 220 kg/m³ make it one of the most efficient rigid insulation materials available for industrial use.

The board’s mechanical strength and durability allow it to withstand long-term exposure to high temperatures without deformation, making it ideal for insulation in industrial furnaces, power plants, and high-temperature piping systems. Standard thickness options range from 4.5 mm to 12.5 mm for sheet sizes of 1.22 m x 2.44 m and 0.6 m x 0.6 m, while block specifications include 50 - 110 mm thickness in 600 mm x 300 mm dimensions. The material is non-combustible, odorless, non-toxic, and resistant to moisture, ensuring reliability in demanding environments.

Industrial buyers in sectors such as metallurgy, petrochemicals, and construction use this calcium silicate board for its high heat resistance, low thermal conductivity, and ease of installation. The product’s asbestos-free composition aligns with modern safety regulations, and its lightweight nature reduces structural load requirements in construction projects. Buyers should confirm exact dimensions, tolerances, and installation guidelines directly with Hongyi Building Material Co., Ltd, as these may vary by order.
