PHA Flexible Grade D — Polyhydroxyalkanoate, Flexible Grade D
PHA Flexible Grade D is a type of biodegradable polymer produced by microorganisms. Its flexibility and toughness make it suitable for films, coatings, and applications where ductility is required, such as flexible packaging or agricultural mulch films. This grade is designed to biodegrade in soil, marine, and compost environments.
