insulation material

It is also called melamine sponge. This product is a flexible, high-opening sound insulation material made of melamine resin foam.

Six characteristics of melamine heat and sound insulation cotton

1) High flame retardancy. After contacting open flame, a dense char layer is formed on the surface of the burning body to block combustion, no dripping, no smoke, no burning, and self-extinguishing when away from the fire.

2) Super strong sound absorption ability. Its high open-pore structure allows sound waves to easily and effectively enter the deep layer of the foam body and transform into vibration energy of the grid to be consumed and absorbed, and effectively eliminate reflected waves.

3) Good thermal insulation. The three-dimensional grid structure effectively blocks the convection heat transfer of air.

4) High temperature resistance. Suitable for long-term work at -180℃~200℃; under instantaneous conditions, there is no decomposition and deformation below 240℃.                 

5) Low bulk density. The bulk density of the product is 4-12kg/m³; it is one of the lightest foam plastics in the world.

6) Green and environmentally friendly. Its stable chemical structure and cross-linking system give it unique chemical stability, fully meeting the national green environmental protection and safety standards for interior decoration, daily necessities, and transportation noise reduction.
