In our experience, however, flexible PVC does not hold up well over the years, especially if subject to warm air. akA02 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. Photographs made using an atomic force microscope and a scanning electron microscope show a multitude of very small particles, typically no bigger than a couple of microns in diameter.
