Web27 apr. 2024 · Poly (butylene adipate-co-terephthalate) (PBAT) is a type of synthetic biodegradable thermoplastic copolyester with comparable mechanical properties to polyethylene, but the application of PBAT is limited by factors such as high cost, short shelf life, poor weather and water resistance. PBAT is marketed commercially as a fully biodegradable plastic, with BASF's ecoflex showing 90% degradation after 80 days in testing. Particular applications that are highlighted by the manufacturers include cling wrap for food packaging, compostable plastic bags for gardening and agricultural use, and as water resistant coatings for other materials, as in paper cups. Due to its high flexibility and biodegradable nature, PBAT is also marketed as an additive for more rigid bi…
