Polyglycolic acid (PGA) is a biopolymer that has great barrier characteristics and is now being used to correct the barrier obstacles from PLA and starch. Water purification: Chitosan has been used for water purification. It is used as a flocculant that only takes a few weeks or months rather than years to degrade in the environment. Chitosan ...
A polymer (/ ˈ p ɒ l ɪ m ər / [4] [5]) is a substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeating subunits derived from one or more species of monomers. [6]
The biopolymer poly-3-hydroxybutyrate (PHB) is a polyester produced by certain bacteria processing glucose, corn starch [46] or wastewater. [47] Its characteristics are similar to those of the petroplastic polypropylene (PP). PHB production is increasing.
An application for this certified compostable and bio-based material is for any kind of plastic films such as shopping bags or organic waste bags. ecovio® can also be used in other applications, like thermoformed and injection moulded articles. Even paper-coating or particle foamed products can be produced by this very versatile biopolymer.
The biopolymer is similar to polystyrene in exhibiting tensile strength and modulus comparable to hydrocarbon-based thermoplastics. Much like polyester , it resists grease and oil. Similarly, it also offers a flavor and odor barrier. [ 6 ]
