Regulatory initiatives in the United States and Europe are accelerating the phase‑out of per‑ and polyfluoroalkyl substances (PFAS) in polymer processing applications, creating a need for alternative polymer processing aids (PPAs) that maintain processing efficiency without the use of persistent fluorinated chemistries. In polyolefin extrusion, high shear stresses and polymer–metal adhesion can induce flow instabilities… Read more »
