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.
PP is a semi-crystalline polymer, its melting point is generally
150~170°C. Compared with PE, PS, and PU foam materials whose
temperature resistance is only 70~80°C, the service temperature of
MPP can reach 120°C, so MPP is especially suitable for high-temperature packaging, high
temperature insulation and other fields.
MPP integrates reinforcement, heat insulation and noise reduction,
and is especially suitable for fields with high requirements for
lightweight materials, such as automobiles, rail transit, ships,
fan blades, etc.
Lightweight and high-strength MPP thick boards are used as
structural foams, replacing traditional structural foams such as
PVC/PU interpenetrating structural foams, PET structural foams,
etc., especially as sandwich composite materials
- Lightweight
- Flat sides
- Self-adhesive
Features
- Permanent flame retardancy ((UL94 V-0, HF-1, B1 rating)
- Excellent thermal insulation (thermal conductivity, 0.035 W/ (m*K))
- Wide weather resistance (negative 180 degrees Celsius to 200
degrees Celsius, up to 240 degrees Celsius, maintaining stable
physical and chemical properties, lightweight PU foam can only
withstand 100 degrees Celsius, 120 degrees Celsius begins to
decompose and fission, glass fibre is fragile in the sub-zero
environment)
- Lightweight (8.5KG/cubic, but lightweight PU foam is the lightest
18 KG/cubic)
- Eco-friendly (does not contain any halogenated hydrocarbons, flame
retardants and/or toxic heavy metals; no toxic and harmful gases
are produced when burning in flames, while lightweight PU foam is
added with flame retardants, and glass fibre is harmful to the
human body). Environmental stability (acid resistance, alkali
resistance, antibacterial, mildew resistance)
- Excellent sound absorption performance (0.95NRC, melamine foam has
better performance in high frequency)
- Secondary processing formability (easy to cut, can be back glued or
laminated, etc.)
