Hydrophobic Melamine Foam – Is Hydrophobic Foam an Effective Widely Available Product?

Hydrophobic Melamine Foam – without and with self-adhesive backing – is certainly an advanced version of the Melamine form with unprecedented water resistance properties that maintain all other crucial attributes for robust deadening – after special treatment, the hydrophobic Foam can achieve a hydrophobic ratio of 99.1 percent. Hydrophobic Foam is exceptionally lightweight (about 6 to 7 kg per m3) and flexible; the Foam’s open-cell surface lets sound waves properly penetrate the foam and simply reflect as an echo. As such, the foam gets recommended for both thermal and acoustical insulation in aircraft, marine, aerospace, architectural, and automotive applications.

Hydrophobic melamine foam also meets international fire safety standards. As such, some of the applications of Hydrophobic melamine Foam include trunk lids, ceilings, and doors.

The Melamine Foam has been cited as eco-friendly, produced without the use of halogenated hydrocarbons or toxic metal flame retardants – Nitrogen gets used to develop the resistance.

Ideally, the lightweight characteristic of the Hydrophobic Foam considerably reduces weight, thereby contributing to energy saving and significantly reduced emissions. For thermal and acoustic insulation applications, one of the most frequently used materials is Melamine Foam insulation.

It is worth noting the Hydrophobic Melamine Foam provides an excellent flame retardant performance, sound absorption performance, wide weather resistance, abrasiveness, and good secondary processing molding performance, which make the foam – thermal insulation, acoustic insulation, heat insulation, flame retardant, heat preservation, cleaning – widely used in professional acoustics, automobile manufacturing, architectural acoustics, automobile manufacturing, rail vehicles, pipeline insulation, aerospace applications, shipbuilding, low-temperature insulation, high-temperature insulation, filtration applications, power stations, large equipment manufacturing, 5G base station, Antistatic, white electrical appliances, industrial cleaning, supercapacitors, furniture manufacturing, daily cleaning, and other critical fields.

So, why choose the Hydrophobic melamine foam? Currently, using effective oil-absorbing materials, particularly the hydrophobic melamine foam, to dispose of oil spilling and oil leak problems seems one of the most useful and economic ways. While there are many shortcomings of the normal absorption materials within the market at the present – such as complicated production processing and environmental contamination, the Hydrophobic Foam remains eco-friendly and relatively simple production processing.

After processing, the Hydrophobic Foam still holds excellent durability and elasticity, which is good for oil reusing and recycling. The foam employs a great thermostability; the Hydrophobic Foam with open-cell characteristics does not have problems with weightlessness until 380 degrees Celsius. And after twelve times recycling, the Melamine Foam still keeps its hydrophobicity. The Hydrophobic Melamine Foam preparation cost remains lower than other materials since a block of Hydrophobic Foam may get used again at least 12 times. After simple processing of the Melamine Foam, the Hydrophobic Melamine Foam comes into shape. Hence, the price for the Hydrophobic Melamine Foam remains reasonable.
