and NF2) and a PFAS-compliant fluorine-based chemistry (A5). A5 is a fluorinated chemistry but is classified as PFAS-compliant because the PFOA and PFOS levels are below 25 ppb. The company can also provide a non-silicone based chemistry. The additives are available as masterbatches in multiple carrier resin options or in fully formulated compounds. The materials are stabilised to withstand high radiant sterilisation exposures. The compounds do not require any injection moulding equipment process changes and do not affect moulded part tolerance requirements, Techmer reported. Labware pipette tips are one application where low fluid retention is crucial. For this application, Techmer said that its additives have been validated with numerous surfactants and organic solutions. In biopharmaceutical manufacturing processes using single-use bioreactors, a low-retention additive can limit the adherence of raw materials to the sides of the vessel, which can help optimise mixing efficiency, said Chow. The additive technology has initially been developed in different grades of PP at various flow rates. The company said that it is working with other polymers to incorporate the technology for
additional applications. Avient recently introduced its Cesa Non-PFAS
Low-Retention Additives, which the company said will be available soon. The additives are manufac- tured without intentionally added PFAS-based or fluorinated raw materials. The additive concen- trates and pre-compounds enhance hydrophobic- ity in injection moulded PP components. In labware and pipette tips, for example, they eliminate the need for secondary low-retention coatings and enable precise fluid dispensing with “virtually no residual liquid left behind,” the company reported.
