In a heat aging test conducted by an independent lab, Reed held dozens of TPV and PVC specimens in a heat aging chamber for 12 weeks at 100C. Material that has been recycled even from old parts exhibits properties almost as good as virgin material as an article in Design News magazine[7] reported on May 5, 2003. Cycle times can be much faster, because the parts do not have to cure in the mold, which is typically two to three minutes for rubber. Also, different grades of TPV and of PVC could yield somewhat different results, but these findings are consistent with most of the literature available. With so many variations and corresponding differences in properties and cost, how do you know which is right for your application? For road and rail construction projects, Santoprene TPV is used for bridge and parking decks, water stops, rail pads and other applications.
