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 an improvement of "a thermoplastic elastomer composition improved in abrasion resistance, anti-marking properties and tearing strength and a method for producing the same" filed by the applicant of the present invention (see Patent Application No. 10-2013-0042206) A supercritical foam injection is possible by using a silica / talc mixture instead of the silica used in the silica cake of the above-referenced patent, and through the supercritical foam injection as described above, the abrasion resistance, In addition, in the supercritical foam injection molding as described above, a general injection mold (a cold-runner mold, not a hot-runner mold) runners) molds, the supercritical foam injection can be performed, and thus the light weight can be secured through supercritical foam injection at a low cost. To a thermoplastic elastomer composition capable of improving abrasion resistance, anti-marking properties, tear strength and lightweight through critical foaming injection molding, and a method for manufacturing the same.
