Heat Insulation Melamine Foam Acoustic Panels Used In Vehicle Manufacturing
MPP foam, a type of closed-cell foam made from polypropylene beads, offers numerous advantages that make it well-suited for NEV battery insulation. Its distinct properties, such as its thermal insulation capabilities, temperature stability, and fire resistance, significantly contribute to the optimal functioning and safety of NEV battery systems.
The exceptional thermal insulation properties and low thermal conductivity of MPP foam are paramount in regulating and maintaining stable operating temperatures within NEV batteries. This is crucial for preserving battery performance and preventing overheating, which can lead to decreased efficiency and potential safety hazards. By minimizing heat transfer, MPP foam ensures that the battery operates within the desired temperature range, thereby enhancing its overall functionality and durability.
Another notable advantage of MPP foam is its versatility in terms of density options and customization. This flexibility allows manufacturers to tailor the foam to meet the specific thermal protection requirements of various NEV battery applications. By selecting the appropriate density, NEV manufacturers can effectively optimize temperature management, guaranteeing that the battery remains in an ideal operating condition and prolonging its lifespan.
In addition to its thermal properties, MPP foam exhibits excellent fire resistance. It is classified as UL94 V-0, which signifies its outstanding ability to resist ignition and prevent the propagation of flames once the ignition source is removed. This fire-resistant characteristic makes MPP foam an ideal material for NEV battery applications, as it helps prevent fire spread and enhances overall safety. In the unfortunate event of a fire, MPP foam can contain the flames and aid in extinguishing them, mitigating potential damage and reducing the risk of injuries.
To summarize, MPP foam offers a reliable solution for NEV battery insulation, ensuring stable operating temperatures and providing fire protection. Its thermal insulation properties, temperature stability, and fire resistance all contribute to the efficient and safe performance of NEV batteries. Incorporating MPP foam into battery systems allows NEV manufacturers to enhance the reliability and safety of their vehicles, further advancing the electric mobility sector while prioritizing customer satisfaction and peace of mind.

It can reach to the grade of GB/T8624-2006 B,DIN510S4,B56853 and UL94 V-0 without adding any flame-retardant media.When it meets fire,it can be decomposed and carbonized but not dropping.Its smoke density is less than 15.It is recommended as No.1 flame-retardant material in the republic places on the book of <<Fire Safety and Flame Resistant Technology in the public places>>which is mainly edited by China Public Secturity Department.
- Heat Stability.The Greencos Foam is belonged to thermal setting plastic with a high grade of three dimensional mesh interconnected structure.It has a high heat stability and anti-aging.The Greencos Foam plastic can work at -180~250 in a long time.
- Health and Safety. Green,Non-Toxic and Odorless,No Fibrosis.
- Antifungal performance. The foam can be processed wasily into piece material and different shape through mechnical way,and it also can be processed into the tapered shape and wedge shape on order to meet the sound absorption requirement. The piece material can be compressed by heating into ceiling and roll material with relief decroative pattern which can absorb sound.At the same time,the surface strength is improved.It is easily dyed and can be manufactured into colorful hanging material for sound absorption.
- Light. 8KG/M3,the lightest foam in the word.

Typical Applications
Acoustic melamine foam
Low-energy buildings become a common understanding. It requires thermal materials to insulate the whole building from the outside. The main purpose is to provide a comfortable indoor climate. In warmer climates or during summer months, good insulation also provides protection against heat. In the winter, heat-insulated buildings save heating energy. Heat losses through external walls and roofs account for more than 75% of the total heat losses in existing buildings. Therefore, thermal insulation is important not only for new construction but also for existing ones.
Melamine foam application
Taking a small single-family house with 100㎡ as an example. The following chart shows that the lower the thermal conductivity value is, the lower costs there will be.
The melamine foam thermal conductivity is 0.034 W/(m•K). It represents that the house insulated by melamine foam will save a family 205€/yr/㎡.
Thermal insulation and soundproofing
Using melamine foam as the thermal insulation material for architecture also helps improve the acoustics of the building. The Noise Reduction Coefficiency (NRC) of melamine foam reaches 0.95 for most medium- and high-frequency sounds.
Melamine foam size and shapes
The normal size of melamine foam we produce is 1250mm in width, 350mm in height, and any size in length. The width of 1250mm meets most industrial requirements. If you have specific requirements, please talk to the sales by email or leave a message.
