3M™ Thermally Conductive Acrylic Interface Pad 5500H is designed to provide a preferential heat transfer path between heat generating components, for example, integrated circuit (IC) chips or electric vehicles batteries and heat spreaders such as aluminum heat sinks. 3M pad 5500H consists of a highly conformable slightly tacky acrylic elastomeric sheet filled with conductive ceramic particles.
FEATURES:
- Easy handling
- High conformability even for non-flat IC surfaces and automotive batteries
- Good flame retardancy, UL 94 V-0 rating
- No siloxane gas/ oil bleeding, which often causes electric connection failure
- Soft compliant material allows for pressure relaxation, preventing high-pressure zones on components
- Good electrical insulation properties
- Slight tack allows pre-assembly. Good wettability for better thermal conductivity
