Description
3M™ Thermally Conductive Acrylic Interface Pad 5590H is a soft acrylic elastomer based interface pad. It has high thermal conductivity, good electrical insulation properties and is ideally suited for applications that require non-silicone properties.
Benefits
- Easy handling and soft pad
- Highly conformability even for non-flat IC surfaces and automotive EV batteries
- Incorporates a thin firm acrylic layer for good handling
- Highly thermally conductive while being electrically insulating
Features
- Slight tack allows pre-assembly
- Good wettability for better thermal conductivity
- Non-silicone acrylic elastome
- Excellent durability for long term conductivity
- UL94 V-0 listed (File No. E176845)
Recommended Uses
- Heat transfer in consumer electronics and automotive electronic products.
- Decrease of compression stress to electronic parts by thermal pad conformability.
