Battery Thermal Management System Thermal interface gap pads flame
retardant properties good thermal insulation
It is a thermal insulation structural part product. It has the
characteristics of high heat preservation, high flame retardancy
and high compressive strength. We can provide corresponding
products according to the different strengths and density needs of
customers. It can be used for heat preservation and heat diffusion
in battery pack module gaps, Pack peripherals and water cooling
plate bottoms, which is conducive to improving battery cycle life
and safety.
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.
