Abstract
A method for manufacturing a plastic dielectric having a plurality of holes and a plastic dielectric manufactured thereby. The method for manufacturing a plastic dielectric includes the steps of: (a) injecting a plastic material into an airtight container; (b) injecting inert gas into the airtight container at pressure of 5 to 9 MPa; (c) maintaining the temperature inside the airtight container at 20 to 50° C.; (d) leaving the airtight container for a predetermined period till an amount of inert gas dissolved in the plastic material becomes 6% wt or more and drawing the plastic material out of the airtight container; and (e) heating the plastic material at temperature of 40 to 110° C.
Claims7
