Potential Use of Reclaimed Propylene Glycol in Manufacturing Unsaturated Polyester Resins

摘要

It seems as if the excitement and concern for using reclaimed materials in the FRP industry has not stabilized to a point at which either suppliers of raw materials and intermediates or the custom molders know exactly how to approach the demands of, "Make it green." Definitions of post-industrial and post-consumer are not clear. Support for those who are attempting to use recycled materials is not evident. Economics are in the wrong direction, and, in the FRP industry, development labs are swamped with every scrap someone has picked up before it went to a landfill to see if it can be used as a filler or reinforcement.
