Abstract
A method of manufacturing a heat conductive molded part having determined heat conductivity properties is provided. The method includes providing a polymer composition containing boron nitride powder. A magnetic field is impressed to the polymer composition containing boron nitride powder, field orienting the boron nitride powder in the polymer composition to a fixed direction. The polymer composition is set containing boron nitride powder with the boron nitride powder oriented in the polymer composition to the fixed direction. The polymer composition may also be provided containing a solvent. The solvent is removed after field orienting the boron nitride powder in the polymer composition to the fixed direction The composition is then set with the field oriented boron nitride powder after having removed the solvent.
