Title:
AUTOMOTIVE COMPONENT
Document Type and Number:
Japanese Patent JP2007191546
Kind Code:
A
Abstract:

To provide automotive components utilizing heat resistance of a stereo complex polylactic acid.

Automotive components are obtained by injection molding, at a mold temperature within a range of 80-130°C, of a polylactic acid (A component) whose ratio of ≥195°C melting peaks is ≥70% in melting peaks in the temperature raising step in (A) differential scanning calorimetry (DSC) measurement, wherein, the polylactic acid comprises a polylactic acid unit (A-1) comprising 90-100 mol% L-lactic acid unit and 0-10 mol% D-lactic acid unit and a polylactic acid unit (A-4) comprising 90-100 mol% D-lactic acid unit and 0-10 mol% L-lactic acid unit and (A-1/A-4) is from 10/90 to 90/10 (weight ratio).
