THERMOPLASTIC ELASTOMER RESIN HAVING EXCELLENT DIP DYEING RESISTANCE

摘要

PURPOSE: Provided is a thermoplastic elastomer resin, which has excellent dip dyeing resistance and thus elongates the service life of products using the resin (for example, antenna covers or ear phone jack covers of mobile phones) by reducing contamination of the products. CONSTITUTION: The thermoplastic elastomer resin having excellent dip dyeing resistance comprises 95-99.5 wt% of a polyester-based thermoplastic elastomer having a Shore hardness D of 25-70 and 0.05-5 wt% of two or more kinds of inorganic pigment. More particularly, two or more kinds of inorganic pigment are selected from the group consisting of antimony trioxide(Sb2O3), calcium carbonate(CaCO3) and talc. Further, the thermoplastic elastomer resin optionally further comprises 0.05-5 parts by weight of a lubricant based on 100 parts by weight of the resin.
