<p>The thermal bonding characteristics of a polyvinyl chloride series resin composition is altered by the incorporation of measured amounts of silicone and, preferably, coated calcium carbonate. This alteration of the resin composition permits the formation of a thermal bond (45) between the resin composition (46) and a compatible material (28), which bond is selectively breakable in response to the application of force which does not cause permanent deformation of the materials, regardless of repeated or prolonged heat exposure. The method is ideally suited for forming frangible connections (45) in medical product implements (10) which must undergo sterilization by autoclaving.</p> |
