A good example of the use of a thermally conductive polymer is the LED lamp pictured below. It is designed for industrial and commercial installations by the UK company Graviton. In this application the heavy cast aluminium design is replaced by a thermally conductive, eco flame retardant modified PA66 heat sink. The end user and moulder particularly like the ease of processing and the high impact which allowed the complex fin structure to be injection moulded.
Witcom offers a wide range of thermally conductive compounds which can be either electrically conductive or electrically insulated. Base resins available include PA66 and PBT.
Witcom BV, part of Wittenburg Group, develops and manufactures specialty engineering plastics compounds. Wittenburg Group has manufacturing facilities in The Netherlands and China. The company is based on a strong research and development ethos, allowing us to deliver technical solutions for highly regulated industries.
