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 high-
performing 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)
