Meldin® 5000 PEEK Based
Meldin® HT Thermoplastics
5000 PEEK Based

Components made with the Meldin® 5000 series (PAEK and PEEK-based material formulations) have several advantages over metals, machined ceramics, and other costly machined materials, with the ease and convenience of thermoplastics. Having a high tensile, compressive and flexural strength, Meldin® 5000 materials are injection molded into tight-tolerance finished components in single or complex designs that can exhibit metal-like finishes without expensive machining or secondary operations, and with the advantages of being lighter and corrosion-resistant.

From a tiny bearing used in hand-held surgical tools to large diameter (>1.5m) seal rings used in offshore oil and gas applications, Omniseal Solutions™ offers a Meldin® 5000 grade that will meet your requirements. Meldin® 5301, Meldin® 5302, Meldin® 5320, and Meldin® 5330 grades provide excellent chemical resistance and thermomechanical properties in addition to superior dimensional stability and physical strength. Meldin® 5055 grade combines these excellent properties with inherent lubricity for higher load-bearing applications.

Meldin® 5000 materials are processed by injection molding into tight-tolerance finished components in simple or complex designs that can exhibit metal-like finishes without expensive machining or secondary operations. There is also availability in hot compression molded or extruded parts, depending on the grade. All grades are available as finished parts, with some grades available as stock shapes to support prototyping.

Is this Material PFAS-Free*?

  • Depending on the application and equipment specifications, we may be able to manufacture this solution PFAS-Free*.

  • * PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.
