Hi, I'm not so well informed on plastics and chemistry to them but I need help finding a plastic that will fit the purposes of my need and uses. I'm looking for a plastic that is clear and elastic(doesn't have to be very elastic), or is the word i'm looking for plasticity, I'm not really sure. Ok, I'll make it easier; the plastic should resist tear upon single use, where it will be presses btwn two hard objects and one of the objects is pointy but not sharp. the plastic will be moulded so it should have a degree of elasicity so it should fit over the object it was initially moulded to fit over. Another thingis that the plastic should be clear and low in cost.
