Material

What Is 1200 kg/m³ Density?

The highest density grade in the range — a denser, harder board with higher compressive capacity and better wear resistance, built for high-load positions where strength and dimensional stability matter more than maximum insulation.

Density Comparison

800 vs 1020 vs 1200 kg/m³

Density	Main Feature	Use
800	Highest strength + low λ (carbon-fibre)	Strength + insulation
1020	Very dense, aluminum-resistant	General heavy industry
1200	Ultra-high density, maximum strength	Heavy duty / structural

Selection

Why Select Density 1200 Instead of Lower Density?

Choose 800

When you need high strength combined with the best insulation (carbon-fibre, low thermal conductivity).

Choose 1020

When you need a balance of density and strength, or resistance to molten aluminum.

Choose 1200

When strength and structural stability are the priority — the densest, highest-strength grade.

FAQ

Frequently Asked Questions

Is density 1200 stronger than density 1020?

Yes. 1200 is the highest-strength grade with compressive strength ≥ 23 MPa (3335 psi) and flexural strength ≥ 15 MPa (2175 psi), above the 1020 grade.

Does higher density reduce insulation performance?

Higher density trades some insulating efficiency for strength. The 1200 grade is chosen for maximum strength and structural stability rather than lowest thermal conductivity; for pure insulation a lower-density grade is more efficient.

Can density 1200 be machined?

Yes. It can be cut, drilled and CNC-machined into custom shapes and supports.

Is density 1200 suitable for industrial furnaces?

Yes. It is used as heavy-duty structural back-up insulation in furnaces, kilns and metal-processing equipment.

Can custom dimensions be supplied?

Yes. Standard and custom sizes, thicknesses and CNC-machined shapes are available on request.
