PFAS-free additives for continuous processes

Wesel, May 29, 2024 – Specialty chemicals manufacturer BYK is providing its customers in the thermoplastics industry with two innovative PFAS-free product solutions that master many current challenges in the production of films, pipes, profiles, fibers and much more. BYK-MAX P 4109 and BYK-MAX P 4110:

  • prevent melt fracture,
  • reduce the viscosity of the melt,
  • reduce die build-up and
  • allow faster material changes.

When processing polyolefins, high shear forces, temperatures and friction sometimes occur in the machines, leading to melt fracture or die build-up. In order to prevent these undesirable side effects and optimize production, fluorine-containing processing aids have often been used to date to ensure good throughput and defect-free finished parts. However, there are currently international legal initiatives to restrict the use of fluoropolymers (PFAS). BYK was quick to develop alternative additives that are PFAS-free and still have the usual positive effect on the process and result.

With BYK-MAX P 4109 and BYK-MAX P 4110, two new polymer processing aids (PPA) from BYK are now on the market that meet these requirements exactly: They are PFAS-free and at the same time allow a high production speed while preventing melt fracture and reducing die build-up which leads to less maintenance and therefore shorter downtimes.

Mode of action of BYK-MAX P 4109 and P 4110

The rapid effectiveness of the two additives cuts long rinsing times and allows fast product changes. In addition, both products are thermostable and are easy to handle.
