3M™ Thermally Conductive Acrylic Interface Pad 5590H is designed to provide a preferential heat transfer path between heat generating components, such as IC Chip or Electric Vehicle (EV) battery, and heat sink or spreader. It consists of highly conformable, slightly tacky acrylic elastomer sheets filled with thermally conductive ceramic particles. These highperforming thermal pads have the following features.

Features
• Easy handling and soft pad
• High conformability even for non-flat IC surfaces and automotive EV batteries
• Incorporates a thin, firm acrylic layer for good handling
• Highly thermally conductive while electrically insulating
• Slight tack allows pre-assembly
• Good wettability for better thermal conductivity
• Non-silicone acrylic elastomer
• Excellent durability
• UL94 V-0 listed (File No. E176845)

Applications

Heat transfer between PCB and heat sink
Thermal management in automotive EV batteries
Power electronics component thermal management
Chip on film (COF) heat conduction
Automotive electronics
LED thermal management
General gap filling in electronic devices
