3M™ Thermally Conductive Acrylic Interface Pad 5590H
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:
Key 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)
