NeoGraf Solutions supplies advanced flexible graphite materials that move heat fast, even in thin, lightweight formats—helping OEMs and Tier 1s tame hotspots, improve uniformity, and slow thermal propagation in EV packs. Flagship eGraf® SpreaderShield™ heat spreaders replace thicker aluminum fins to cut mass and channel heat efficiently to cold plates during charge/discharge.
With more than a century of graphite innovation, NeoGraf’s portfolio spans heat spreaders, TIMs, thick graphite laminates, fire-protection additives, and high-temperature seals—building blocks that drop into today’s battery modules and pack architectures.
Key Technologies Supporting EV Battery Systems:
SpreaderShield™ Flexible Graphite Heat Spreaders
Thin, die-cuttable heat spreaders that replace aluminum cooling fins to reduce pack weight by ~20–40 kg per vehicle, lower hotspot temperatures, and help limit cell-to-cell propagation by routing heat to the cold plate.
HiTherm™ Graphite TIMs
Compliant, sheet-based thermal interface materials that drive out interfacial air gaps and cut contact resistance; through-plane conductivity up to ~10–16 W/m·K with very high in-plane conduction for lateral spreading—ideal under baseplates and busbars.
NeoNxGen™ Thick Flexible Graphite
Single-layer, high-performance graphite (UL 94 V-0) for “thick” heat paths, shields, and fin geometries where multiple layers were once required—simplifying assembly while sustaining ~900–1100 W/m·K in-plane conduction.
GrafGuard® Expandable Graphite (Fire Protection)
Non-halogenated, intumescent graphite additive for foams, coatings, and barrier walls that forms a char layer, absorbs heat, and displaces oxygen—supporting pack-level fire-protection strategies without melamine-based FRs.
GraFoil® Flexible Graphite Seals & Gaskets
High-temperature, chemically resistant sealing materials for coolant plates, manifolds, and battery housings—maintaining integrity where elastomers can degrade.
Whether in battery systems, power electronics, or structural modules, NeoGraf’s graphite innovations—SpreaderShield heat spreaders, HiTherm TIMs, NeoNxGen laminates, GrafGuard fire protection, and GraFoil seals—are enabling lig
