The PEEK insulated electric wire which has excellent heat-resistant characteristics

摘要

We have been continuously carrying out the foundation research and investigation of various engineering plastics for the application of the electrical wires and cables. Among the various engineering plastics, as for a PEEK material, it is well known as its excellent heat-resistant, electrical and mechanical properties, therefore it has been applied as the insulation material of for the special type of cables. Previously, we have established the special process technique to obtain its performance to the full by the method of controlling the crystallization. On the other hand, recently, the demand of its application as the insulation material, especially very high temperature rating (around 300°C), increased and examination on the performance in high temperature was carried out. In this report, the characteristics and the performance of a peek insulated electric wire is presented.
