Polyhydroxyalkanoate

polymer

Polyhydroxyalkanoate (PHA) is a family of biodegradable thermoplastic polyesters synthesized by bacterial fermentation, offering a bio-based alternative to conventional petroleum-derived plastics. PHAs are used in packaging, biomedical implants, and agricultural films where biodegradability and compostability are critical requirements; they are notable for their ability to degrade in marine and terrestrial environments, making them suitable for applications where persistent plastic pollution is a concern, though they typically command higher material costs and may require specialized processing conditions compared to commodity polymers.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
