Abstract
Disclosed herein is a method for evaluating scratch resistance of a plastic resin comprising scratching a surface of a test sample of plastic resin using a scratch apparatus to form a scratch of the surface having a scratch profile; scanning the scratched test sample with a surface profile analysis apparatus to measure the scratch profile; and creating a scratch resistance evaluation index based on the measured scratch profile to evaluate the scratch resistance of the test sample. The method has good reliability and reproducibility, reduces measurement time and errors caused by measurers and measuring conditions, provides easy measurement and can be widely applied to all plastic resins.
