Polymers are a highly diverse class of materials which are available in all fields of engineering from avionics through biomedical applications, drug delivery system, bio-sensor devices, tissue engineering, cosmetics etc. and the improvement and usage of these depends on polymer applications and data obtained through rigorous testing. The applications of polymeric materials and their composites are still increasing rapidly due to their below average cost and ease of manufacture. This in turn fuels further development in research. Better understanding of the materials properties in diverse environments and temperature ranges is central to sourcing the correct polymer materials to suit the application.
