Ii. Principle:
After being heated uniformly at the specified temperature and time, the aging characteristics of the sample are determined by observing its properties such as yellow resistance, glue opening, shrinkage, elongation and residual rate before and after aging.
This instrument is designed to meet ASTM-D2436, CNS3556,742 standards
