ADDITIVES | THERMALLY CONDUCTIVE
grades of its Makrolon polycarbonate can improve performance, reduce weight by over 40%, reduce the number of assembly operations, and cut costs by as much as 20%, in comparison with designs that use aluminium heat sinks.
Sensitivity required Meanwhile, at Swiss independent compounder Polycompound, Business Development Manager Jan Schweizer says it is crucial to have the right equipment to produce TC compounds “as many of the used additives are sensitive and are to be handled carefully in the compounding process.” Polycompound has been involved in the

production and development of thermally conduc- tive compounds from a very early stage, he says. The company has been involved in the develop- ment of various projects and has proven to have the right machinery using co-kneader-technology for such compounds. “The products produced for partners have not only shown great thermally conductive values on the development lines but Polycompound was also able to reproduce the same values when scaling-up the production quantity to several tonnes in recent months,” Schweizer says.
