Abstract
The effects of Salviae Miltiorrhizae(SM) on aging properties of RVNRL films are studied with heat aging method. The results show that SM can effectively improve RVNRL films' aging properties. SM a is the best aging agent among SM,SM w and SM a. The SM a(c 1999) content is suitable to improving aging properties of RVNRL films, It is found that aging properties of SM a are different which come from different regions.
