Problems solved by technology

[0006] In order to solve the problem that the insulating material used for triple-layer insulated wires in the prior art has good insulating performance, but because of its high texture, it is easy to break and crack, resulting in insulation failure, and then provides a soft texture that can be bent at will. Insulating material for triple insulated wire without cracking and triple insulated wire using the same

Abstract

The invention provides a heat-resistant insulating material, which comprises PET, PEN and PBT. In parts by weight, the PET is 30-70 parts, the PEN is 15-60 parts, and the PBT is 3-40 parts. Preferably, the heat-resistant insulating material further includes 1-2 parts of color masterbatch and 1-4 parts of compatibilizer. In addition to good insulation performance and flexibility, the material also has good high temperature resistance and heat resistance performance, and its insulation performance can basically be maintained in F-class high temperature environment. Furthermore, the three-layer insulated wire with the above heat-resistant insulating material as the insulating layer meets the requirements of class F heat-resistant insulation.
