The primary reason is that most design engineers are not experienced with plastics, since their education and training have prepared them for designing with metals. Furthermore, the chemical nature of plastics coupled with the extremely large number of plastics makes it often difficult for designers without specific training to properly understand and differentiate between kinds of plastics. The myriad grades and formulations only complicate the problem.
