Both melamine foam and polyurethane foam are relatively common cleaning, sound-absorbing and heat insulating materials in our lives, so what is the difference between melamine sponge and polyurethane foam in these application?

1. Melamine Foam VS Polyurethane Foam In Cleaning Application

Although melamine foam is soft to the touch, melamine foam is actually a very hard material with a very high porosity of 99.9%. Because melamine foam has a hard texture and high porosity, melamine foam has strong adsorption and can easily remove stains on the surface of objects. In contrast, polyurethane foam is a relatively soft material that can also clean out stains, but the cleaning effect is not nearly as well as melamine foam.

2. Melamine Foam VS Polyurethane Foam In Sound Absorbing Application

As shown in the table above, both melamine foam and polyurethane foam are good at sound absorbing. However, the sound absorption effect of polyurethane foam is better than that of melamine foam between 250-500 Hz, and the sound absorption effect of polyurethane in other audio segments are not as good as melamine foam.

In addition, due to the flammability of polyurethane foam, polyurethane foam cannot be used in industry, and it is more suitable for installation in the room. However, melamine foam has excellent flame retardancy, without adding any flame retardant, the flame retardant level of melamine foam can reach B1. Thus melamine foam is more widely used in sound absorption, for example, melamine foam can be used in automobiles, high-speed rail, aircraft carriers, KTV, cinemas, theaters, etc.

3. Melamine Foam VS Polyurethane Foam In Heat Insulation Application

The working temperature of melamine foam can reach -200~240℃, which has good high temperature and low temperature resistance. Melamine foam is widely used in heat thermal insulation, especially works well in heat thermal insulation of industrial pipes.

However, the high temperature resistance of polyurethane foam is general, especially the humidity and heat resistance is not good, the normal use temperature range of polyurethane foam is -40~120℃. Due to the flammability of polyurethane foam, it can't be used for engineering heat preservation, fire prevention and heat insulation. Polyurethane foam is commonly used for home thermal insulation, such as filling sofas and mattresses with polyurethane foam.

4. Melamine Foam VS Polyurethane Foam In Other Aspects

Polyurethane foam is less expensive to manufacture, resulting in lower procurement costs, on the contrary, melamine foam is slightly more expensive than polyurethane foams due to the complex foaming technology.

Polyurethane foam can be dyed into different colors according to needs. Due to the high porosity rate of melamine foam, it is easy to dye them unevenly. Therefore, the melamine color is only white and gray (natural color), pink (high density melamine foam can be dyed).

As mentioned above, melamine foam and polyurethane foam have their own characteristics, and customers can choose foam according to your own use and needs.
