All About Melamine Foam from SINOYQX?

Melamine Foam Overview

What is Melamine Foam? (Wikipedia)

Melamine foam is a foam-like material consisting of a melamine-formaldehyde condensate. It is known for its unique porous structure and has a range of applications due to its sound-absorbing, thermal insulating, and cleaning properties.

How to Make Melamine Foam

Melamine foam is produced through a polymerization process involving melamine and formaldehyde. The process generally includes:

  1. Polymerization: Melamine and formaldehyde are polymerized to form a resin.
  2. Foaming: The resin is foamed by heating it with a blowing agent, creating a cellular structure.
  3. Curing: The foam is then cured and further processed to achieve the desired properties.

Main Properties of Melamine Foam

  • High Sound Absorption: Due to its open-cell structure, melamine foam is excellent for acoustic applications.
  • Thermal Insulation: Provides good thermal insulation properties.
  • Lightweight: Very low density, making it easy to handle and install.
  • Fire Resistance: Naturally flame retardant.
  • Chemical Stability: Resistant to many chemicals and solvents.
  • Durability: Maintains its properties over time without significant degradation.

Main Traditional Applications of Melamine Foam

  • Soundproofing: Used in studios, auditoriums, and buildings to reduce noise levels.
  • Thermal Insulation: Applied in buildings and appliances for insulation purposes.
  • Cleaning Products: Marketed as “magic sponges” for household cleaning.

Is Melamine Foam Toxic?

Melamine foam itself is generally considered safe for use in various applications, including cleaning products (like the Magic Eraser) and acoustic insulation. However, there are a few points to consider regarding its safety:

  • Dust and Particles: When cutting or sanding melamine foam, it can produce dust or small particles that may be inhaled. It’s advisable to wear a mask and work in a well-ventilated area to avoid respiratory irritation.
  • Chemical Composition: Melamine foam is made from melamine-formaldehyde resin. In its finished form, the foam is stable and not toxic. However, during manufacturing, formaldehyde—a known irritant and potential carcinogen—is used. Finished melamine foam products typically contain very low levels of residual formaldehyde, generally considered safe for use.
  • Heat and Combustion: Melamine foam has fire-resistant properties, but if it is exposed to very high temperatures( such as over 300°c or open flames, it can decompose and release toxic gases such as carbon monoxide and ammonia.

Overall, melamine foam is safe for typical consumer and industrial applications when used appropriately.

Specific Applications and Comparisons

Melamine Acoustic Foam

Melamine acoustic foam is specifically designed for sound absorption. It is used in environments where controlling noise is critical, such as recording studios, theaters, and industrial settings.

Melamine Foam vs. PU Foam

  • Melamine Foam:
    • Superior sound absorption.
    • Naturally flame retardant.
    • Higher cost.
    • Better thermal insulation properties.
    • Versatility
  • PU Foam (Polyurethane Foam):
    • More versatile and widely used.
    • Typically, cheaper.
    • Can be made with various properties for different applications.
    • Generally, less fire-resistant without additives.

Melamine Thermal Insulation Panel

These panels are used in construction and appliances to provide thermal insulation. They benefit from melamine foam’s low thermal conductivity and high thermal stability.

  2. Scotch-Brite Easy Erasing Pad (3M)
  3. Melamine Foam Eraser Sponge (various generic brands)

Is Melamine Foam Dangerous?

Melamine foam itself is considered safe for most applications. However, like many industrial products, it should be handled according to safety guidelines to avoid inhalation of dust during cutting or sanding, and to prevent exposure to its components before they are fully polymerized and cured.

New Applications of Melamine Foam

Melamine Thermal Insulation Pad for New Energy Battery

Melamine Foam Filtration Roll for Air and Liquid

Melamine foam can be used in filtration systems to purify air and liquids, thanks to its high porosity and ability to trap fine particles.

Melamine Foam Aerogel for New Energy Battery Thermal Insulation

Melamine foam is a very good aerogel-loaded substrate because of its nanoscale pore size and uniform pores; melamine foam compounded with aerogel can effectively improve the thermal conductivity, and can be used as a heat-insulating pad for new energy batteries.

Modified Melamine Foam

Modified melamine foam is enhanced with additional properties such as increased durability, hydrophobicity, or specific chemical resistance. Products include:

  • Hydrophobic Melamine Foam: Used in oil spill cleanup and water-resistant applications.
  • Reinforced Melamine Foam: For higher mechanical strength and durability.
  • Shielding & Wave Absorption: SINOYQX modified melamine foam is able to provide excellent shielding & wave absorption performance with its patented technology with light weight
