2. Ozone cracking - Wikipedia

   en.wikipedia.org/wiki/Ozone_cracking

   However, it does occur in many other safety-critical items such as fuel lines and rubber seals, such as gaskets and O-rings, where ozone attack is considered unlikely. Only a trace amount of the gas is needed to initiate cracking, and so these items can also succumb to the problem.

3. Neoprene - Wikipedia

   en.wikipedia.org/wiki/Neoprene

   Neoprene's burn point is around 260 °C (500 °F). [21] In its native state, neoprene is a very pliable rubber-like material with insulating properties similar to rubber or other solid plastics. Neoprene foam is used in many applications and is produced in either closed-cell or open-cell form.

   Thermoplastic vulcanizates were first reported in 1962 by A.M. Gessler and W.H. Haslett. [4] In 1973, W.K. Fisher reported the dynamic vulcanization process through his prior work on polypropylene and EPDM rubber-based TPVs with peroxides as a cross-linking agent.

6. Materials for use in vacuum - Wikipedia

   en.wikipedia.org/wiki/Materials_for_use_in_vacuum

   Indium wire is used as a gasket in demountable seals. Gold wire is used as a gasket in demountable seals for ultra-high vacuum, as well as an alternative to lead-tin solder for making electrical connections. Platinum is a highly chemically inert material with high cost and low outgassing. Zirconium is corrosion-resistant.
