Shrinkage Test for Reflective Film

Take the 230 mm * 230 mm retro-reflective sheet as the sample of the shrinkage test, and place it under the standard test condition for 1 hrs at least. Remove the release paper, place the sample on the smooth surface, and make the binder upward. Measure the dimensional change of sample for the reflective film after the release paper is removed for 10 min and 24 hrs respectively.
