General Purpose Melamine Foam - Versatile Insulation & Cleaning Solutions

Melamine Foam (CMF) Product Introduction​

Melamine Foam (MF), also known as melamine foam, is a novel flexible foam material with an open-cell three-dimensional network structure (open-cell rate up to 99.99%) produced by microwave high-temperature foaming of melamine resin. It combines extremely light weight, excellent elasticity, outstanding flame retardancy, efficient sound absorption, superior thermal insulation, and safe hygiene, making it a high-performance multifunctional material.

​Core Characteristics​

  1. ​Excellent Flame Retardancy​
    • Without adding any flame retardants, it achieves the highest flame retardancy rating (e.g., UL94 V-0). Upon exposure to open flame, its surface rapidly carbonizes, isolating oxygen, without melting or dripping. It self-extinguishes upon removal from the flame and produces extremely low smoke toxicity, offering significantly higher safety than many traditional foam materials.
  2. ​Outstanding Sound Absorption​
    • Thanks to its open-cell rate of over 99%, sound waves easily penetrate deep into the foam body and are converted into grid vibration energy for efficient dissipation. It is particularly effective in absorbing mid-to-low-frequency noise, eliminating reflected waves, and purifying the acoustic environment.
  3. ​Excellent Thermal Insulation​
    • The three-dimensional network structure effectively blocks air convective heat transfer, giving it excellent thermal insulation properties with low thermal conductivity. It also exhibits remarkable temperature resistance and a wide working temperature range.
  4. ​Safe Hygiene and Environmental Friendliness​
    • It is chemically stable, non-toxic, odorless, and free of fiber and dust shedding. Its hygiene performance meets stringent requirements (e.g., food contact grade). The foaming agents used in production are more environmentally friendly, and the product is recyclable.
  5. ​Exceptional Cleaning Ability​
    • Its fine nano-scale capillary open-cell structure enables efficient adsorption of stubborn stains through physical friction. Only water is needed, without chemical cleaners, making it a powerful daily cleaning tool known as “magic sponge”.
