While I agree with much you post Rob, I'm curious about your statement that they could deform and slip. Have you used them and personally seen this to be the case? Is there a test out there that I'm not aware of that shows that these stoppers deform more under load than their steel/aluminum/brass counterparts? More importantly, what the difference in deformation between all these materials is in a given type of rock? I haven't seen that evidence but would be very interested in looking at it if you wouldn't mind posting it up.
Given enough time, most polymers will form cracks. Unlike metals, plastics do not have a regular microstructure because they are made of long-chain molecules. Even so-called "crystalline" polymers are largely amorphous tangles with islands of regular stacking (called "spherulites") embedded in them.
