Solviva® Biomaterials

Specialty Polymers for Implantable Medical Devices

Click to enlarge

Solviva® is a family of biomaterials offered for use in implantable medical devices. Only products designated as part of the Solviva® family of biomaterials may be considered as candidates for medical applications implanted in the human body and devices that are in contact with bodily fluids or tissues for greater than 24 hours.

Solviva Biomaterials meet or exceed the highest industry standards in terms of quality and biological safety. Products are available for prolonged exposure (greater than 24 hours to less than 30 days) and permanent exposure (greater than 30 days) to bodily fluids and tissue in the human body.

Solviva products can be sterilized using all conventional sterilization methods, including gamma radiation, ethylene oxide and steam.

More to Offer than PEEK

The Solviva family of biomaterials includes four distinct polymer chemistries, providing more options for meeting the needs of implantable devices used in orthopedics, cardiovascular, spine and more.

Zeniva® PEEK (polyetheretherketone)is one of the most biostable plastics available with high strength and stiffness plus excellent toughness and fatigue resistance. Zeniva PEEK meets the requirements of ASTM F2026-07 as a polyetheretherketone (PEEK) polymer for surgical implant applications.

Veriva® PPSU (polyphenylsulfone)provides unsurpassed toughness combined with transparency and excellent biocompatibility.

Eviva® PSU (polysulfone)offers practical toughness in a strong, transparent polymer. It is also available in opaque white.

The entire line of Solviva® Biomaterials is manufactured in compliance with ISO 13485 and under the relevant aspects of current Good Manufacturing Practices. Solvay’s biomaterial manufacturing processes are carefully validated and enhanced controls provide product traceability. In addition, all materials are tested in an accredited lab that is ISO 17025 compliant.


Solviva® Biomaterials, as medical device raw materials, are considered biocompatible based on the requirements of ISO 10993-1:2009 for long term implants. Detailed Master Access Files (MAF) are registered with the FDA to support our customer’s submissions for regulatory clearance.
