High density calcium silicate board (bulk density 820 kg/m³) N-17 grade reinforced with carbon fibre. Ultra high compressive strength ≥21 MPa, flexural strength ≥7.6 MPa, low thermal conductivity and excellent dimensional stability with only 0.2% shrinkage at 850°C.
This is the N-17 grade high density calcium silicate board reinforced with carbon fibre, providing exceptional mechanical strength and thermal performance for the most demanding industrial applications.
With a bulk density of 820 kg/m³, compressive strength of ≥21 MPa and flexural strength of ≥7.6 MPa, this product offers one of the highest strength-to-density ratios available in calcium silicate insulation materials.
The carbon fibre reinforcement significantly enhances toughness and impact resistance while maintaining excellent thermal insulation properties with low thermal conductivity.
Standard Size: 1230 × 1230 mm, thickness 6–160 mm; 1250 × 2500 mm, thickness 10–80 mm; 1200 × 600 mm, thickness 10–160 mm (custom sizes and shaped products available)
