Stress High Temperature Insulation
MPP foam, a type of closed-cell foam derived from polypropylene
beads, offers a range of benefits that make it highly suitable for
insulation in NEV batteries. The unique properties of MPP foam,
including its thermal insulation, temperature stability, and fire
protection capabilities, contribute to the optimal performance and
safety of NEV battery systems.
With its exceptional thermal insulation properties and low thermal
conductivity, MPP foam effectively regulates and maintains stable
operating temperatures within NEV batteries. This is crucial for
preserving battery performance and preventing overheating, which
can lead to reduced efficiency and potential safety hazards. By
minimizing heat transfer, MPP foam ensures that the battery
operates within the desired temperature range, enhancing its
overall functionality and longevity.
One of the advantages of MPP foam is its versatility in density
options and customization. This flexibility allows manufacturers to
tailor the foam to meet the specific thermal protection
requirements of different NEV battery applications. By selecting
the appropriate density, NEV manufacturers can effectively optimize
temperature management, ensuring that the battery remains in an
ideal operating condition.
In addition to its thermal properties, MPP foam boasts excellent
fire protection capabilities. It is classified as UL94 V-0,
indicating its outstanding resistance to ignition and
non-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 the spread of fire
and improves overall safety. In the unfortunate event of a fire,
MPP foam can contain the flames and aid in extinguishing them,
minimizing potential damage and reducing the risk of injury.
Overall, 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-resistant nature contribute to the efficient
and safe performance of NEV batteries. By incorporating MPP foam
into battery systems, NEV manufacturers can enhance the reliability
and safety of their vehicles, promoting the advancement of electric
mobility while prioritizing customer satisfaction and peace of
mind.
| SN. | Advantage | Description |
| 1 | Rigidity and Toughness | Existing foam materials are either hard and brittle, or soft and
tough, and it is difficult to have both rigidity and toughness. The
microporous polypropylene foam material has both rigidity and
toughness, which complements the deficiency of the performance of
the existing foam material. |
| 2 | Environmental Protection | The MPP foaming process is clean and pollution-free, and it can be
recycled and reused. It is an environmentally friendly product. |
| 3 | High Temperature Resistance | The thermal deformation temperature of PP foam material is much
higher than that of PS and PU foam materials. |
| 4 | Thermal Insulation | The micron-sized cells effectively reduce the convection of gas in
the foam, thereby effectively reducing the heat transfer caused by
air convection. |
| 5 | Lightweight | The density of MPP foam is generally below 50kg/cm³. |
| 6 | Waterproof | Micron-sized cells make its extremely low water absorption. |
