Polymers are used in a range of materials, including common household goods, clothing, toys, construction materials, insulation, and numerous other products. Chemically speaking, they are compounds with molecules bonded together in long, repeating chains. They are often man-made, using petroleum derived, non-renewable resources. Common petrobased polymers include:
Biobased polymers can be direct or "drop in" replacements for petroleum-derived polymers and offer near-identical properties, or they can offer entirely novel characteristics. The importance of reducing dependency on fossil fuels for environmental reasons has brought about a surge in the production of these products. Some polymers that may include biologic feedstock are TPU, PE, and PLA.
Common uses include:
Bio-Based Polymers - Bio-based polymers, also called bio-based resins, are obtained from renewable resources (algae, bacteria, microorganisms, plants, etc.).
