ANTISTATIC POLYLACTIC ACID-BASED RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide polylactic acid-based resin foaming particles having≥30 times expansion ratio usable as a shock absorbing material, good moldability and≤1×1012Ω/sq surface intrinsic resistance usable as a shock absorber for electron precision equipment and the like, foam-molded products of the same and a resin composition for attaining the same. SOLUTION: The foam-molded product of the polylactic acid-based resin is produced by using a polylactic acid-based resin composition comprising 100 pts.wt. polylactic acid-based resin having 92/8-8/92 isomer ratio (L form/D form) of the lactic acid component and 1-3 pts.wt.≤20C secondary alkanesulfonic acid sodium salt, impregnating a foaming gas into the composition and foaming the composition.
