Virgin PEEK: Unfilled PEEK and Stock Evidence

Unfilled PEEK is polyetheretherketone without the specified reinforcing filler of a filled grade. Virgin is a sourcing description that needs an agreed definition. Material reference.

Unfilled PEEK and Stock Evidence

For a machined component, clarify whether the requirement excludes reprocessed material, additives or both. Do not assume that virgin means medical approved or that every unfilled PEEK stock shape has the same processing history. Compare reinforcement only where the design needs it.

Manufacturing and acceptance checks

Request the exact resin and stock grade, traceability and the supplier's declaration supporting the virgin requirement. Define temperature, load and chemical exposure, plus final dimensions and surface finish. Qualify the finished part under the actual service conditions before approving another source.
