Is the quality of plastic used to fabricate O&P products really that important?
Yes it is. For many years when plastic was first introduced to the O&P marketplace they were using plastic that had not been stress-relieved. That material also had a lot of regrind in it instead of being virgin material. That grade of plastic is primarily used for industrial uses where quality is not an issue. For medical purposes you want the material to be as stable as possible in order to have successful pulls – the first time. O&P Enterprises only sells stress relieved virgin material.
