• High performance filler  and polymer technology

• Phase change at 45°C

• Highly conductive filler  loading to optimize  performance

• Superior handling  and reworkability 

• Superior reliable  thermal performance 

• Available in both pad  and paste formats

Honeywell PCM45F, a highly thermally conductive Phase Change  Material (PCM), was designed to minimize thermal resistance at  interfaces. 

Based on a novel polymer PCM system, Honeywell PCM45F-SP this material exhibits  excellent wetting at interfaces during typical operating temperature  range, 

resulting in very low surface contact resistance. It is available  in both pad and paste/printable formats. 

A proprietary filler material provides high thermal conductivity (2.0–5.0  W/m˚C) and a low thermal impedance (<0.20˚C cm2/W), 

suitable for  high performance IC devices.
