Real Time Ageing of Polymeric Components in Closed Systems

  • G. F. Hayes

Abstract

Results from real time ageing of polymeric components in closed systems are discussed and compared with data from accelerated ageing studies. Polymers considered have included polysiloxanes, polychloroprenes, polyurethanes, polyimides and epoxies. The polymeric materials have been exposed to oxidative and reducing atmospheres and radiative, thermal and mechanical stresses. Test conditions and the results of changes in physical and chemical properties are described and related to the chemistry of the materials. Valuable data can be obtained from accelerated ageing studies but real time ageing data are required to support and confirm specific trends in ageing phenomenology.
