The search for alternatives to chemicals called PFAS has been going on for years. Recently, materials design company Techmer PM created one—a new chemical for use in polymer processing.

The new solution: Last year, the Clinton, Tennessee–based manufacturer introduced the HiTerra T5—a polymer processing aid that helps maintain film surface smoothness and die-lip buildup—which replaces traditional chemistry based on per- and polyfluoroalkyl substances.

• The HiTerra T5, which meets Environmental Protection Agency guidelines and does not interfere with other additives, is being used in large-scale commercial undertakings by Techmer PM customers.

Why it’s critical: In March, the EPA issued the first federal reporting limits and guidelines for tracking the use of PFAS in manufacturing, along with other PFAS-related regulations. Individual states are also imposing their own restrictions on PFAS chemicals.

• The current regulatory environment is motivating plastics processors and raw materials suppliers to seek new alternatives to this chemistry.
• “The biggest challenge is that fluorinated chemistry is excellent at reducing friction, reducing melt fracture, improving hydrophobicity, stain resistance and helping the processing that manufacturers use, for example, to make film,” Techmer PM CEO Mike McHenry told the NAM in a recent interview. “It also helps with wear on small gears. It’s very effective, and it has unique properties that customers are accustomed to.”

More replacement efforts: Techmer PM is working closely with its customers to come up with additional PFAS alternatives, McHenry said.

• Because one of PFAS’ most useful characteristics is its ability to resist fire, “we’re looking at ways to remove halogen flame retardants, including fluorinated compounds” and find a comparable alternative for customers, McHenry said.
