Selecting the right resin for industrial extrusion lines is one of the most important decisions in the plastics manufacturing industry. Choosing the wrong material not only reduces product quality, but can also lead to increased waste, production downtime, higher maintenance costs, and turn the entire factory into an expensive machine for generating industrial problems. Humans still treat plastic as if it were one single material, then act surprised when products start warping under heat like overcooked spaghetti. An impressive engineering philosophy, truly.
