Medium Density Calcium Silicate Board Manufacturer & OEM Supplier
MINDELUN supplies medium density calcium silicate board for industrial thermal insulation, equipment insulation, and customized insulation components. With five nominal density options ranging from 400 to 800 kg/m³, our calcium silicate insulation boards offer different combinations of mechanical strength and thermal performance for industrial applications.
Designed for applications requiring rigid insulation materials, MINDELUN calcium silicate boards are available in thicknesses from 20 to 120 mm, with standard and customized dimensions subject to production requirements. We also support CNC machining, special-shaped fabrication, and OEM packaging for eligible orders.
As a calcium silicate board OEM supplier, we work with insulation distributors, industrial equipment manufacturers, engineering contractors, and other B2B buyers seeking customized insulation products and reliable technical support.
Key Features of Calcium Silicate Insulation Board
1. Five Density Grades for Different Requirements
MINDELUN calcium silicate board is available in nominal densities of 400, 500, 650, 750, and 800 kg/m³. This range allows buyers to compare mechanical strength, weight, and insulation properties when selecting a suitable grade.
Higher-density grades generally offer greater mechanical strength within this product range, while the appropriate choice depends on the actual installation and performance requirements.
2. Thermal Insulation for Industrial Applications
Calcium silicate insulation board helps reduce heat transfer in properly designed thermal insulation systems. The supplied product specifications state a maximum service temperature of 1000°C.
Actual suitability depends on the selected density grade, operating temperature, exposure duration, and installation conditions. Buyers should consult the applicable technical data before using the board in high-temperature equipment.
3. Mechanical Strength and Rigid Structure
Depending on the selected grade, the specified minimum bending strength ranges from 1.5 to 8 MPa, while minimum compressive strength ranges from 3 to 17 MPa.
These properties help buyers evaluate the board for applications where handling, installation, and mechanical support are important.
4. CNC Machining and Custom Fabrication
In addition to standard boards, MINDELUN supports CNC machining and customized cutting according to approved drawings and manufacturing feasibility.
Available customization options can be discussed for:
- Non-standard board dimensions and thicknesses.
- Precision-cut insulation components.
- Special-shaped boards and machined parts.
- OEM packaging and private-label requirements.
