Seqens’ R&D centers provide extensive expertise in tailor made-polymers design to meet your needs. Our portfolio of polymers, all manufactured under GMP standards, includes:


  • Expansorb® portfolio of PLA/PLGA copolymers used as functional excipients for controlled and slow drug release (weeks to months) with a single injection. We can provide small or bulk quantities for screening PLA/PLGA ± PEG polymers (up to 50 references available) to improve formulation during early-stage development.

Vitamin E TPGS

  • Vitamin E TPGS (Vitamin E, D-alpha-tocopheryl polyethylene, glycol, 1000 succinate), a water-soluble derivative of natural Vitamin E, widely used as an excipient in drug delivery systems because it acts as a solubilizer and enhances permeability to improve bioavailability of poorly absorbed drugs.

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.

Catalog on demande

Seqens also offers development of other cGMP medical grade polymers such as hydroxybutyrate, (poly)ester, acrylate and methacrylate copolymers.
