METHERM Microporous M 1000 Max — High-Strength Microporous Board, Max 1000°C
METHERM Microporous M 1000 Max high-strength fumed silica microporous board, max 1000°C. Flexural strength 0.13 MPa for vibration-exposed and mechanically loaded installations. Distributed by ThermalEast for buyers needing robust microporous insulation.
Buyer Brief
METHERM Microporous M 1000 Max is specified when mechanical robustness governs the installation — not minimum thermal conductivity. The "Max" grade achieves flexural strength of 0.13 MPa versus 0.12 MPa for standard M 1000, through higher reinforcing fibre loading. The trade-off: thermal conductivity is 0.021 W/(m·K) at 20°C and 0.040 at 800°C (vs 0.020 and 0.033 for M 1000). If the installation is mechanically benign and pure thermal performance is the criterion, specify standard M 1000 instead.

Use Cases
Kiln Car Deck Insulation. Kiln car decks in tunnel and shuttle kilns must support ware weight and survive repeated thermal cycling to 900–1000°C. M 1000 Max's higher flexural strength reduces breakage from forklift point loads and extends replacement intervals.
Vibration-Exposed Furnace Positions. Backup insulation near burner ports, blower systems, and conveyor drives is subject to crack propagation under sustained cyclic loading. M 1000 Max's higher fibre loading resists this failure mode better than standard M 1000.
Multi-Step Handling Installations. Boiler shell retrofits and modular furnace builds requiring panels to be fitted, trimmed, and re-handled impose bending loads that exceed standard-grade tolerance. M 1000 Max reduces waste from board damage during installation.
Furnace Door and Frame Components. Door panels and frame insulation subject to repeated mechanical cycling and occasional impact — in high-cycle shuttle kilns and continuous annealing lines — specify M 1000 Max over standard M 1000.
When to Choose M 1000 Max vs M 1000
Specify M 1000 Max when vibration, handling, or mechanical loading governs the installation. Specify standard M 1000 when the position is mechanically benign and minimum lambda is the priority. Specify M 1100 when service temperature exceeds 1000°C.
Why ThermalEast
ThermalEast sources M 1000 Max directly from the manufacturer at direct-mill pricing — typically 30–50% below equivalent European-sourced microporous panels — with full material certification and export documentation.
