PCL

polymer

Polycaprolactone (PCL) is a synthetic aliphatic polyester with a low melting point and semi-crystalline structure, commonly used as a homo- or copolymer in medical devices, packaging, and additive manufacturing. It is valued in biomedical applications for its biocompatibility and biodegradability, particularly where controlled degradation over months to years is required. PCL is also popular in 3D printing and as a plasticizer or blend component because of its processability and ability to impart flexibility; it serves as a lower-cost alternative to more hydrolytically unstable polyesters in non-critical applications.

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.
