Cemtherm®
Cemtherm® is an asbestos free thermal insulating laminate manufactured from cement and reinforced with organic fibres. It is suitable for applications which require high strength, thermal stability or electrical insulation. Cemtherm® is an ideal material for replacement of asbestos cement based products and can be supplied silicone coated or impregnated for improved moisture resistance. Temperature: Up to +530°C, +700°C short term.
Key features:
- Strong.
- Rigid.
- Excellent insulation properties.
- Non combustible.
- Low thermal conductivity.
- Excellent impact resistance.
Applications: Machined components, muffle plates, core plates, support plates, gripper pads, end plates.
