· PCL· Polycaprolactone

Polycaprolactone (PCL) is a semi-crystalline aliphatic polyester synthesized by ring-opening polymerization of ε-caprolactone, valued for its biodegradability and processability at moderate temperatures. It is widely used in biomedical applications—including sutures, drug delivery systems, and tissue engineering scaffolds—as well as in flexible films, adhesives, and 3D printing filaments, where its combination of low melting point, high elongation capability, and slow degradation in physiological environments makes it preferable to faster-degrading polymers like PGA or more rigid alternatives.

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.
