FAQ
Phase change material (PCM) is a thermal interface material (TIM) that transitions from solid to soft when it reaches its phase change temperature. In this state it flows into all surface irregularities, expels air from micro structures and creates full-area thermal contact between component and heat sink. The result is an extremely low thermal resistance — achieved reliably from the very first heat-up cycle.
Unlike thermal grease, phase change material is dry to the touch before assembly — eliminating smearing, uneven bondline thickness and dosing errors. Thermal grease must be applied as a liquid, is prone to pump-out under mechanical stress and requires precise application. PCM simplifies assembly significantly and delivers reproducibly low thermal resistance with process-reliable coating thicknesses.
HALA offers phase change materials in five types: polyimide film with PCM coating, pure PCM film, aluminium film with PCM coating, pyrolytic graphite film with PCM coating, and pre-applicable printable PCM compounds in cartridges for fully automated pre-application.
Yes, phase change materials from HALA are silicone-free — making them ideal for automotive applications, aerospace and any process where volatile siloxanes would contaminate painting lines, electrical contacts or assembly environments. For silicone-free gap filling solutions, see our silicone-free gap fillers.
Phase change material is used wherever the lowest possible thermal resistance and process-safe assembly are required: power modules with MOSFETs and IGBTs, thermo-electric modules, e-mobility power electronics and high-performance CPUs in servers and industrial computers. Its dry pre-assembly capability makes it particularly attractive for automated production lines.
Yes, HALA supplies phase change materials as sheets, rolls, kiss-cut parts and loose die-cut parts — with or without adhesive, fully or partially coated, in different PCM coating thicknesses. Printable compounds are available in cartridges for automated dispensing. Request a free sample or expert consultation.
