Avient introduces non-PFAS low-retention additive for pipette tips
Last update on Dec 3, 2025
Avient Corporation highlighted its range of polymer colorants and additives to enhance the appeal, performance, and sustainability of healthcare products at Medica 2025.
This includes the introduction of its latest Mevopur™ Healthcare Functional Additive, a non-PFAS, low-retention compound for pipette tips.
Eliminating the need for secondary low-retention coatings
Avient’s Mevopur portfolio includes performance and processing-enhancing additives that can reduce friction, improve clarity, enable laser marking and welding, and offer protection against ultraviolet (UV) light, oxidation, and gamma and/or e-beam sterilization.
The new, low-retention materials solution, formulated without intentionally added per- and polyfluoroalkyl substances (PFAS), slip agents, plasticizers, or biocides, can be used to enable excellent fluid release from polypropylene pipette tips in scientific and medical laboratory settings.
Available as a ready-to-use compound, this low-retention additive solution eliminates the need for secondary low-retention coatings and can be adapted to customer requirements. It can also withstand typical electron-beam and gamma radiation sterilization doses applied to pipettes (usually up to 15 kGy) with fast recovery of hydrophobicity post-radiation. Additionally, its raw materials are pre-tested to ISO, USP, and ICH Q3D protocols for manufacturers who wish to use medical-grade materials for their pipette tips.

“This non-PFAS low retention additive technology not only delivers effective hydrophobicity without fluorinated substances; it’s also developed and manufactured under a holistic change control program. This can help to reduce the risk of performance and quality issues that could occur from changes in raw materials and manufacturing process,” says Volker Dickfeld, senior marketing manager Healthcare Global for Color & Additives at Avient.
