METHOD FOR PRODUCING ECO-FRIENDLY POLYMERIC COMPOUND WITH INCREASED HYDROLYSIS RESISTANCE AND HEAT RESISTANCE, MULTI-LAYERED INSULATING WIRE USING SAME, AND PRODUCTION METHOD THEREOF

摘要

The present invention relates to a multi-layered insulating wire which includes an insulating layer made of a branched polyolefin resin of which the melting point of at least two layers out of insulating layers excluding an outermost layer is greater than or equal to 200°C. The outermost layer is coated and insulated with a highly heat resistant polymeric resin which is able to stand heat up to 250°C, enabling the production of eco-friendly multi-layered insulating wire with increased hydrolysis resistance and heat resistance in an easy way.;COPYRIGHT KIPO 2017
