The Rise of MPP Foam: The Preferred Insulation Material for New Energy Vehicle Batteries

Revolutionizing the realm of insulation materials for new energy vehicle batteries, MPP foam has emerged as the unparalleled preference, owing to its exceptional performance and an array of advantages. With its distinctive combination of rigidity and toughness, this closed-cell polypropylene thermoplastic foam effectively addresses the limitations of conventional foams, elevating performance and reliability to new heights. Moreover, its environmental friendliness and recyclability further establish it as an eco-conscious choice, aligning with the principles of sustainable development.

Understanding MPP Foam

MPP foam is a thermoplastic foam composed of closed-cell polypropylene, boasting a pore size of less than 100 microns. Its unique attributes include rigidity, toughness, heat resistance, insulation capability, lightweight construction, and waterproof properties.

The Advantages of MPP Foam

Rigidity and Toughness: Through extensive testing, MPP foam has exhibited outstanding compression curve and tensile strength, surpassing the limitations of existing foam materials. By seamlessly combining rigidity and toughness, MPP foam effectively overcomes the performance deficiencies of traditional foam materials.

High-Temperature Resistance: MPP foam surpasses PS and PU foam materials in terms of heat distortion temperature, enabling it to attain a V0 flame retardant grade. This exceptional feature ensures stability and performance even in high-temperature environments.

Thermal Insulation: The micron-level pores within MPP foam significantly reduce gas convection, resulting in a thermal conductivity of less than 0.05 in our tests. This reduction in air convection enhances its thermal insulation properties, minimizing heat transfer.

Lightweight Construction: With a density typically below 100kg/cm3, MPP foam contributes to reducing the overall weight of automotive applications.

Water Resistance: The micro-sized cells of MPP foam exhibit minimal or no water absorption, providing long-term protection against moisture-related issues.

Environmental Friendliness: MPP foam is manufactured using clean, non-polluting processes and is both recyclable and reusable, making it an environmentally conscious choice.

Applications in New Energy Vehicles

MPP foam finds extensive application in thermal protection for new energy vehicles, particularly as a battery pack insulation material. By effectively reducing heat transfer, MPP foam enhances battery performance and lifespan. Its usage spans various areas within battery modules, including the upper cover, inside the pack, and more, where it provides cushioning, support, and thermal insulation. Notable applications include 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 the module and top cover, pre-molded insulation shells, and other critical areas requiring temperature control. The lightweight nature of MPP foam aids in reducing vehicle weight, thereby improving energy efficiency and extending mileage.

MPP foam's exceptional high-temperature resistance surpasses that of other foams, ensuring stability and performance in harsh thermal conditions. The micro-sized cells contribute to excellent insulation properties, effectively reducing heat transfer and enhancing overall battery performance. During the charging and discharging process, new energy vehicle batteries experience rapid heat generation and expansion. MPP foam effectively isolates temperature conduction between battery components, while its pressure resistance and shock absorption capabilities minimize battery deformation, expansion, and bulging, thereby enhancing battery lifespan and safety.

Additionally, the lightweight property of MPP foam contributes to weight reduction in new energy vehicles, thereby improving energy efficiency and extending driving range. Its low water absorption further enhances its water resistance, safeguarding batteries against moisture-related problems. By incorporating MPP foam into battery packs and critical components, manufacturers can ensure superior thermal protection, improved performance, and longer service life. The widespread adoption of MPP foam in the automotive industry paves the way for more efficient and sustainable thermal management solutions.

As the new energy vehicle market continues its rapid expansion, the unmatched properties of MPP foam are poised to revolutionize battery insulation. Its versatility and effectiveness position it as the premier choice for ensuring the safety, performance, and longevity of battery systems within the new energy vehicle industry.
