cGMP Medical Polymer Synthesis
Seqens’ technical and manufacturing teams have successfully completed countless cGMP medical-grade polymer synthesis projects, including:
- Drug delivery technology
- Excipients
- Medical devices (510k)
- Medical-grade coatings
- Therapeutics
These projects begin in our laboratories, to enable our teams to improve many polymerization processes and to adopt the latest analytical techniques supporting their development. Seqens has the capacity to produce our cGMP polymers in quantities ranging from kilos to tons.

Recent Polymer-Related Projects
PEKK polymers
- PEKK (Poly-Ether-Ketone-Ketone) polymers, which are useful for long-term implantable human devices with a life cycle of several years. These polymers are widely used as orthopedics, neurological, dental, spinal and cardiovascular implants as well as in PEKK-based 3D-printed bones.
Seqens also offers development of other cGMP medical grade polymers such as hydroxybutyrate, (poly)ester, acrylate and methacrylate copolymers.
