Engineers, acousticians, and manufacturing buyers choose high-density melamine foam when a component must stay dimensionally stable, resist flame, and absorb noise in the same build; this hub maps those capabilities to demanding insulation, acoustic, and safety-critical projects, then points you to the full melamine foam for industrial range for format and grade comparison. https://melaminefoams.com/products/high-density-melamine-foam https://melaminefoams.com/collections/melamine-foam-for-industrial
This is a hot-pressed open-cell thermoset foam. The heat-and-pressure step improves density, hardness, rigidity, toughness, edge definition, and dimensional stability compared with regular melamine foam, while retaining the material’s intrinsic thermal insulation, flame retardance, and sound absorption.
The same hot-pressed chemistry can be supplied as dense blocks, flat sheets, CNC-processed shapes, protective inserts, and melamine-foam sponge products.
Each demanding environment prioritizes a different set of product facts. Use these modules to align the application with the specification that matters.
Flame-retardant grade GB8624-2012 B1, UL94 V0/HF-1, plus a service temperature range of -200 °C to +240 °C.
Buyer decisionStart with the fire classification and operating temperature, then choose thickness between 2.0 and 50.0 mm for building, ceiling, and HVAC insulation programs.
Open-cell sound absorption reaches NRC 0.90 at 80 mm and NRC 0.85 at 50 mm, with rigid edges that hold clean geometry.
Buyer decisionConfirm the target panel thickness and density first; then use precision cutting to integrate acoustic cores into furniture, wall panels, ceiling inlays, and equipment enclosures.
Hot-pressed density improves toughness and dimensional stability over broad temperature ranges, while CE, Rohs, and Halogen reports support compliance reviews.
Buyer decisionDefine maximum part dimensions, density target, and custom-shape requirements, then request CNC-processed samples before production.

Specifications are listed for the high-density product page and should be confirmed against the exact grade, density, and thickness you plan to specify.
Choose the application type, then move from product fact to a clear buying decision.
Buyer decision: specify the project fire class first, then select sheet dimensions and thickness before requesting a quote for the building component.
Buyer decision: set the acoustic target in NRC, choose the panel thickness that meets it, then confirm the density grade and CNC tolerance.
Buyer decision: define maximum part size, density, quantity, and edge-finish requirements; use CNC processing for contoured or insert parts.
Send your target density, thickness, dimensions, and compliance requirements to the supplier team. Quotes can include custom cutting, sheet formats, and finished component specifications.

Melamine foam rolls supplied by reliable melamine foam manufacturers. Developed for large scale acoustic and thermal insulation projects with stable material output.
View productthe product page lists a density range of 10.00 to 80.0 kg/m³. higher-density grades increase hardness and rigidity while retaining thermal insulation, flame retardance, and sound absorption.
the material passes gb8624-2012 b1 and ul94-2013 v0 and hf-1 tests. this makes it suitable for safety-conscious construction, hvac, and industrial product design projects.
according to the product page, the service temperature range is -200 °c to +240 °c. physical stability across this range helps minimize deformation during fabrication and operational use.
sound absorption is measured at nrc 0.85 for 50 mm thickness and nrc 0.9 for 80 mm thickness under gb/t18696.1-2004.
compared with regular melamine foam, the hot-pressed version offers higher density, higher hardness, and stronger toughness, while retaining flame retardance, thermal insulation, and sound absorption.
yes. standard production includes white or grey color, maximum length 1500 mm, maximum width 1200 mm, and thickness from 2.0 to 50.0 mm. cnc processing and engraving are available for special shapes.
