Polyester-based heat-shrinkable tube for covering condenser and its preparation method

摘要

Disclosed is a polyester-based heat-shrinkable tube for covering a condenser that includes a polyester resin or a copolymer polyester resin as a principal component and an external particle such as talc or silica to have a slipperiness in a defined range, the polyester-based heat-shrinkable tube being applicable to a high-speed covering process on a condenser due to its good slipperiness to enhance the efficiency of working and, after covering and shrinking steps, tightly coupled to the component part of the condenser under dry heat treatment, thus securing effectiveness in protection and electrical insulation of the condenser.
