Was caused.
In addition, when mounting or fixing to an automobile body as an automobile interior material, the automobile interior material is exposed to a harsh environmental condition of high temperature and high humidity for a long time,
In particular, dimensional stability under moist heat conditions becomes a problem. For example, in a slide type sunshade where only both ends are supported by rails, when the elongation is large under wet heat conditions, it deforms so as to hang down, and it becomes impossible to open and close, causing a serious problem. there were.
