Cross-Linked Polypropylene Foam — Superior Shock Absorption & Uniform Cell Compression for Battery Pack Longevity
EKKOFLEX's IXPP (Irradiation Cross-Linked Polypropylene) foam sheet is a high-performance closed cell foam engineered for EV battery pack compression and vibration dampening. With a compression set below 5% (ASTM D3574) and excellent vibration dampening (Tan Delta > 0.15), this cross-linked PP foam maintains consistent cell-to-cell pressure throughout the battery pack lifecycle.
The irradiation cross-linked molecular structure delivers superior mechanical recovery with over 95% compression rebound, ensuring long-term dimensional stability under constant compression loads. At 2mm-8mm thickness, this versatile foam sheet absorbs road-induced vibrations and mechanical shocks while providing uniform pressure distribution across battery cell surfaces.
