Betaseal TC thermal-conductive interface material from DuPont is a solution for battery pack assembly. Part of the offering comprised of DuPont’s AHEAD (Accelerating Hybrid-Electric Autonomous Driving) initiative, Betaseal TC is designed to be easy to apply, retain thermal-conductive properties between the battery cells and cooling plate, and have low pullout force to facilitate ease of battery module removal for repair/reuse/recycling.

Betaseal TC is a dispensable thermal interface material demonstrating benefits that include non-abrasive formulation; fast dispensing (compression or injection process compatible); fast joining, with low press-in force; no sagging in vertical aging test; long working time of 30 minutes; no physical change over aging; and ease of repairability, with low pullout force.

DuPont says the material can be robotically applied for production efficiencies through repeatable processes for high-volume assembly environments. It can also be manually applied for smaller volumes or repairs. Betaseal TC ensures retention of thermal conductivity due to good contact between the battery cells and the cooling plate, with no material gaps.
