P(3HB)

polymer

Poly(3-hydroxybutyrate) or P(3HB) is a naturally derived thermoplastic polyester that belongs to the polyhydroxyalkanoate (PHA) family, produced through bacterial fermentation or chemical synthesis. It is a biodegradable polymer notable for its ability to decompose in various environmental conditions (soil, marine, compost), making it a sustainable alternative to conventional petroleum-based plastics for applications where end-of-life disposal is a critical concern. P(3HB) is used in packaging films, agricultural mulches, medical implants, and tissue engineering scaffolds, though its brittleness and lower processing flexibility compared to polyethylene or polypropylene typically limit its adoption to niche markets where biodegradability justifies performance trade-offs.

Regulatory Screening

Environmental

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.
