Premix

PRETHERM TPE 1050 is a novel thermoplastic elastomer based highly thermally conductive compound intended primarily for heat dissipation. It may also find interesting uses as gap filler between processor and heat sink or co-molded into plastic shell. Thermal conductivity is achieved with Boron nitride which is highly thermally conductive and electrically isolating. PRETHERM TPE 1050 can be injection-molded like an ordinary thermoplastic elastomer thus giving great new possibilities in gasket design and mass production. It has adhesion to selected thermoplastics and metal contacts are also arranged. This opens up interesting construction possibilities with co-injection molding e.g. molding the gasket directly in the phone casing. Recyclability is an added value. The material is silicone free.
