| Abstract: |
| Several high performance specialty elastomers with special properties which can be applied in the field of non-tire rubber products and used under harsh environments in recent years are reviewed.Part 5 of this review introduces the blistering and bursting damage of elastomeric parts（e.g. seals） caused by explosive decompression or rapid gas decompression in high pressure and high temperature oil and gas
field systems，as well as the varieties and types of anti-explosive decompression elastomers. Anti-explosive decompression elastomers must pass relevant internationally recognized standard testing and certification and obtain a certificate of conformity before they can be supplied to users in the oil and gas industry. Main certification testing standards，including NORSOK M-710（Norway），NACE TM 0297（America），TOTAL GS EP PW 142（France）and ISO 23936-2 are listed. Among them，NORSOK M-710 is the most widely used. In addition，formulations and properties of some performance elastomers for anti-explosive decompression are cited. |
