PBAT High Heat — Poly(butylene adipate-co-terephthalate), High Heat Grade BB
PBAT High Heat Grade BB is a modified copolyester offering enhanced thermal stability compared to standard PBAT. This improvement allows it to withstand higher temperatures during processing and in end-use applications, making it suitable for hot-fill packaging or components exposed to moderate heat, while retaining its biodegradability.
