Flame-retardant polypropylene microcellular foam (MPP) is a porous foam material made by using polypropylene (PP) as the substrate to form a large number of micron-sized bubbles in the body through clean supercritical carbon dioxide technology.

MPP foam is a closed-cell foam made from polypropylene beads that provides exceptional thermal insulation, low thermal conductivity, and excellent temperature stability. As a battery insulation material, MPP foam is highly suitable for NEV batteries, which require stable operating temperatures to ensure optimal performance and safety.

MPP foam is available in various densities and can be customized to meet the specific thermal protection requirements of different NEV battery applications. With its low thermal conductivity and excellent insulation performance, MPP foam ensures that NEV batteries maintain a stable operating temperature, reducing the risk of overheating or damage to the battery.

MPP foam also has excellent fire protection properties, classified as UL94 V-0, indicating its outstanding resistance to ignition and non-propagation of flames once the ignition source is removed. These fire protection properties make MPP foam an ideal material for NEV battery applications, helping to prevent the spread of fire and improve overall safety. In the event of a fire, MPP foam can help to contain the flames and extinguish them, reducing the risk of damage and injury.
