THERMOPLASTIC POLYESTHER-BASED ELASTOMER RESIN COMPOSITION HAVING ANTISTATIC FUNCTION

摘要

PURPOSE: A thermoplastic polyesther-based elastomeric resin composition is provided to secure the excellent antistatic property regardless of the season, and to protect a spare part using the composition from dust and other contaminants. CONSTITUTION: A thermoplastic polyesther-based elastomeric resin composition contains the following: 95~98wt% of thermoplastic polyester elastomeric resin with a structure formed with a hard segment and a soft segment; and 2~5wt% of anion antistatic agent, for 100wt% of the composition. The anion antistatic agent is potassium alkyl benzene sulfonate, sodium alkylbenzene sulfonate, or their compound. The hard segment of the thermoplastic polyester elastomeric resin is a compound produced by polymerizing aromatic dicarboxylic acid and low class diol. The soft segment of the thermoplastic polyester elastomeric resin is a polyalkylene oxide.
