Experiments are carried out based upon ASTM 5510 instead. Films are placed in an oven to perform aging process. The optimal operating condition change heat aging temperature 70℃and 100℃，Elongation of the aged specimens could drop to 5%。
Plastics Industry Development Center has obtained the certificate of Tire 2 of ISO 14855 (for biodegradability test) as well as the CNLA verification. Verification from CNLA for tire 3 (toxic materials test) based on ASTM D6400 is expected to be accomplished by the end of this December.
