Embodiment Construction
[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0010] An insulating material for earphone wires, the insulating material is made by mixing thermoplastic polyester elastomer TPEE and high-density polyethylene HDPE, the mixing ratio of thermoplastic polyester elastomer TPEE and high-density polyethylene HDPE is based on the insulating material It is used to control the thickness of the insulating layer for the earphone wire. Table 1 shows a set of mixing ratios and insulating layer thickness obtained after experiments. The model of thermoplastic polyester elastomer TPEE used in the experiment is Hytrel5526. The model of high-density polyethylene HDPE is Dow 3364.
