MPP foam has become the first choice for new energy vehicle battery insulation materials due to its excellent performance and many advantages. The unique combination of rigidity and toughness solves the limitations of existing foams and improves performance and reliability. In addition, its environmental friendliness and recyclability make it an environmentally friendly choice for sustainable development.
What is MPP foam?
This closed-cell polypropylene thermoplastic foam has a pore size of less than 100 microns and offers unique rigidity, toughness, environmental friendliness, heat resistance, insulation, lightweight and waterproofing properties.
Advantages of MPP foam
1. Rigidity and toughness: MPP foam has excellent compression curve and tensile strength in our tests. Overcoming the limitations of existing foam materials, MPP foam combines rigidity and toughness, and solves the performance deficiencies of traditional foam materials.
2. High temperature resistance: Compared with PS and PU foam materials, MPP foam has a higher heat distortion temperature and can reach V0 flame retardant grade, which ensures stability and performance in high temperature environments.
3. Thermal insulation: MPP foam in the micron-level pores can effectively reduce gas convection inside the foam, in the test of our thermal conductivity are less than 0.05, can minimize the air convection caused by heat transfer, enhance the thermal insulation properties.
4. Light weight: MPP foam density is generally less than 100kg/cm3, which helps to reduce the overall weight of automotive applications.
5. Water Resistant: Micron-sized cells give MPP foams very low or no water absorption, ensuring long-term protection against moisture-related problems.
6. Environmentally friendly: MPP foam is produced using clean, non-polluting processes and is recyclable and reusable, making it an environmentally friendly choice.
Application in new energy vehicles:
MPP foam can be widely used for thermal protection in new energy vehicles. It can be used as thermal insulation material for battery packs, effectively reducing heat transfer and improving battery performance and life. It is mainly used in the upper cover of the module, inside the Pack, etc., to play the role of cushioning, support and thermal insulation. At present, we have successfully applied it to buffer pads between battery cells, module foam pressure strips, case side insulation patches, water-cooling plate and bottom guard plate buffer pads, buffer pads between module and top cover, pre-molded insulation shells, and so on. In addition, it can be used to insulate electronic components, electrical distribution systems and other critical areas where temperature control is essential.The lightweight nature of MPP foam helps to reduce the overall weight of the vehicle, improving energy efficiency and range.
The high temperature resistance of MPP foam exceeds that of other foams, ensuring stability and performance under harsh thermal conditions. The micron-sized cell gives it excellent insulating properties, which effectively reduces heat transfer and improves the overall performance of the battery. During the charging and discharging process, the batteries of new energy vehicles will rapidly exothermize and contract and expand, and MPP is able to isolate the temperature conduction between the battery components. At the same time, MPP has sufficient pressure resistance and shock absorption buffer performance, which can maximize the prevention of battery deformation and expansion and bulging, and improve the service life and safety of the battery.
In addition, the lightweight property of MPP foam helps to reduce the weight of new energy vehicles, improve energy efficiency and extend mileage. Its low water absorption makes it highly water resistant and protects the battery from moisture problems. By using MPP foam in battery packs and critical components, new energy vehicle manufacturers can ensure superior thermal protection, improved performance and longer service life, and the widespread use of MPP foam in the automotive industry is paving the way for more efficient and sustainable thermal management solutions.
As the new energy vehicle market continues to grow, the unique properties of MPP foam will be a game changer in battery insulation. Its versatility and effectiveness make it the first choice for ensuring the safety, performance and longevity of battery systems in the new energy vehicle industry.
