Melamine sponge has been widely used in high-end packaging industries such as high-end cosmetics, high-end gifts and high-end health products. The product has good whiteness and never yellowing, and can be cut and die-cut according to the specifications of the outer box.
Melamine foam is a new type of low-density (4-12kg/m3), high-opening three-dimensional grid structure based on melamine resin substrate. Its unique chemical structure and three-dimensional mesh The system has unique chemical and physical stability and does not age or decompose in weak acid and weak alkali environments.
High flame retardancy: It can reach the German DIN 4102 B1 grade and the US UL 94-96 V-0 grade high flame retardant material standard without adding flame retardant.
High sound absorption: Its open porosity of more than 97% enables sound waves to enter the deep layer of the foam conveniently and efficiently, and the vibration energy of the mesh can be consumed and absorbed, and the reflected waves are effectively eliminated.
Good thermal insulation: its open porosity is over 97%. The low thermal conductivity three-dimensional grid structure effectively blocks the convective heat transfer of air.
Strong temperature resistance: suitable for long-term operation under the conditions of -150 ° C to 180 ° C, no decomposition and deformation at -180 ° C to 240 ° C.
Low bulk density: The product has a bulk density of 4-12kg/m3, which is the lightest foam at present.
Non-toxic hygienic safety: Its stable chemical structure and cross-linking system make it unique chemical stability, fully meeting the green environmental safety standards in the packaging field.
