70C Hardness Supercritical Carbon Dioxide Technology MPP Foam Sheet
For Backpack
Microcellular Polypropylene foam is a porous foam made from a
polypropylene base material with a large number of micron-sized
bubbles formed in it by clean supercritical carbon dioxide
technology.
FR-MPP foam sheet : the lithium-ion battery cell cushioning sheet
1.Sealing and fastening of battery housings
FR-MPP10 sheet is the preferred solution for sealing and protecting
battery housings with very good compression and deformation
properties, outputting stable stresses over a wide range of
deformations to protect them from potential damage caused by the
elements and road debris.
2.Matting on the bottom of the battery housing
Applied between the battery housing and the shield, the FR-MPP15
sheet is able to compensate for assembly tolerances and insulating
cushioning.
3.Anti-shock pads to isolate vibrations
Packing is also required between batteries to absorb internal shock
energy. Vibration must be managed both within the pack and between
the pack and the vehicle. FR-MPP25 resists collapse caused by the
stresses of compression and temperature, extending the life of the
battery by continuing to seal and absorb shocks.
