Photo-degradation of natural rubber films for natural gas application
Natural rubber (NR) can be degraded depending on various factors such as heat, mechanical force, chemical reaction, and light. Light is an attractive factor because it degrades NR under low temperature and pressure. In this research, the photo-degradation of NR films was carried out to investigate t...
