NR high density calcium silicate boards are ideal insulation materials for aluminum casting, foundry industries, and different high temperature industrial furnace structure insulation.
NR-85 boards can withstand a temperature up to 1000 °C and it can be contacted directly with molten metals, we have different bulk density and strength boards available to meet clients’ requirements, the density ranges from 800 kg/m3 to 1200 kg/m3 and typical dimensions are 2400x1200 or 1200 x 1200mm, thickness is from 20mm up to 140mm.These boards have an excellent structural strength and dimensional stability.
Good resistance to thermal shock,Dimensionally stable and precision
Non-wetted by molten aluminum or other non-ferrous metals
Non-reactive to lubricants such as boron nitride or graphite
With proper installation and maintenance, High Density Calcium Silicate Boards can last for several decades, typically ranging from 30 to 50 years or more. Their longevity is attributed to their robust composition, which includes a mixture of calcium and silica reinforced with fibers, making them highly resistant to wear and tear. These boards are also impervious to moisture, mold, and pests, which further extends their lifespan. Regular inspections and minor maintenance, such as sealing any cracks or reapplying protective coatings, can help maximize their durability and ensure they remain in optimal condition for many years.
High Density Calcium Silicate Boards should be stored in a dry, well-ventilated area. Ensure they are placed on a flat surface to prevent warping and maintain their structural integrity over time. Proper ventilation helps in avoiding any moisture accumulation.
Avoid exposing the boards to moisture and direct sunlight. Use protective coverings if necessary to shield them from environmental factors that could compromise their quality and performance. Keeping them away from extreme temperatures also helps in preserving their durability.
