THERMOPLASTIC ELASTOMER COMPOSITION OF ENHANCING ABRASION RESISTANCE, MARKING PREVENTING FUNCTION, TEAR STRENGTH AND NET WEIGHT USING THE SUPERCRITICAL INJECTION FOAMING MOLDING AND METHOD FOR MANUFACTURING THEREOF

摘要

The present invention is a modified version of ″a thermoplastic elastomer composition with enhanced abrasion resistance, anti-marking properties, and tear strength, and a method for manufacturing the same″ previously applied (patent application number 10-2013-0042206) by an applicant of the present invention. More specifically, the present invention relates to a thermoplastic elastomer composition capable of enhancing abrasion resistance, anti-marking properties, tear strength, and lightness through supercritical foaming injection molding, and a method for manufacturing the same. The present invention: enables supercritical foaming injection by using a silica/talc mixture instead of silica used for silica cake in the previously applied patent; ensures not only abrasion resistance, anti-marking properties, tear strength, but also lightness through the supercritical foaming injection; and obtains lightness properties through the supercritical foaming injection at low cost, by enabling the supercritical foaming injection even if a general injection mold (a cold-runner mold) is used, instead of a hot-runner mold, with the respect to the supercritical foaming injection.
