High performance plastics differ from standard plastics and engineering plastics primarily by their temperature stability, but also by their chemical resistance and mechanical properties, production quantity, and price. There are many synonyms for the term high-performance plastics, such as: high temperature plastics, high-performance polymers, high performance thermoplastics or high-tech.

Department of Energy's Office of Scientific and Technical Information. 1 Material Properties of Plastics Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions.

Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure ). These characteristics also figure prominently in the environmental lifetimes of polymers or plastics. Recently, reports of microbial degradation of polymeric materials offer new emerging technological opportunities to modify the enormous pollution threat incurred through use of polymers/hotellewin.com: John A.

Glaser. improves the radiation stability by times. Radiation-crosslinking of fluoro-polyimide at elevated temperature also greatly increases its stability, including its resistance to hydrolysis. Another novel technique for enhancing polymer stability is through blending a.

Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.

Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the.

stability. In an earlier study, PP2’s OIT under air flow conditions of ml/ min was determined and the result compared with the same film sample (about micron in thickness) after 20 kGy of gamma dose. When the data was plotted in the Arrhenius form in Figure 1, it is clearly seen that the gamma exposure has significantly reduced the OIT.
