The foam material also has a three-dimensional grid structure with an open-cell rate of over 99%, which not only allows sound waves to be effectively transformed into grid vibration energy and consumed and absorbed, showing excellent sound insulation performance, but also effectively blocks the convection heat transfer of air. In addition, its unique thermal stability makes it have good heat insulation and insulation properties.
Furthermore, Yadina’s soft melamine foam plastic has a density of only 8-10Kg/m3, making it highly processable. It can work in environments ranging from low temperatures of -200℃ to high temperatures of 200℃. It is widely used in the fields of building construction, sports fields, factory equipment, electronic products, automobiles, power batteries, high-speed rail, aviation, and navigation. It is especially suitable for sound absorption, noise reduction, vibration reduction, insulation, and heat preservation under fire retardant and high-temperature conditions. Yadina’s melamine foam plastic also has miraculous cleaning capabilities and high water absorption and moisture retention, making it widely used in areas such as soilless agriculture and ink cartridges.
Yadina’s soft melamine foam has a width of up to 1300mm, a height of up to 400mm, and can be customized in length. The 1300mm width meets the requirement of many industrial sheet materials with a width of 1000mm.
Yadina’s soft melamine foam comes in white, gray, or other customized colors. Various sizes and profiles can be customized according to customer requirements to meet the needs of different places.
The conventional packaging material used is polyethylene plastic film.
By using Yadina melamine foam and profiles, the following deep processing for different fields can be carried out:
Yadina melamine foam can be processed into single-piece products by cutting and pressing. It can also be processed into sheet and complex irregular geometric shapes by machining methods such as shaping, cutting, and milling, and the surface can be processed into conical or chevron-shaped sound-absorbing products to meet the sound-absorbing requirements
In order to color or improve mechanical properties, Yadina melamine foam can be coated on the surface by spraying, rolling, and coating.
3、Connection and immersion：
Due to its excellent chemical resistance, ordinary adhesive materials such as acrylic resin can be used for connecting Yadina melamine foam. Solvent-based and reactive resin adhesives can also be used under consideration of their chemical resistance. Excess liquid can be extruded by a twin-screw extruder to speed up the drying process.
Yadina melamine foam sheets can be made into embossed sound-absorbing ceilings and rolls by hot pressing molds, while the surface strength is also improved. They can be easily combined with materials such as metal foil, textiles, and non-woven fabrics to produce a series of sound-absorbing, insulation, and thermal insulation products to meet the needs of different places and working conditions.
5、Water and oil repellency:
The water and oil repellency of the surface-treated Yadina melamine foam can be used in other special fields.
