Technical Data | July 2020 3M™ Thermally Conductive Acrylic Interface Pad 5590H Product Description 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) Product Construction/Material Description Thermally conductive conformable layer Thermally conductive firm layer (less tack) permanent PET liner (outside of roll) Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. 3M™ Thermally Conductive Acrylic Interface Pad 5590H Property Value Color Base resin Thickness Filler type Very low tack layer Low tack layer White/Gray Acrylic 0.5, 1.0mm, 1.5 mm, 2.0 mm (thicker pads available upon request) Ceramic Good for re-workability and handling, light gray color-permanent layer Soft, good thermal conductivity, white color 3M™ Thermally Conductive Acrylic Interface Pad 5590H Applications • Heat transfer in consumer electronics and automotive electronic products • Decrease of compression stress to electronic parts by thermal pad conformability Examples: o Heat transfer between PCB and heat sink o Thermal management in automotive EV batteries o Power electronics component thermal management o Chip on film (COF) heat conduction o Automotive electronics o LED thermal management o General gap filling in electronic devices Typical Physical Properties and Performance Characteristics Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.
