A non-fluorinated polymer processing aid that removes melt fracture and die build-up in PE and LLDPE film, for converters moving away from PFAS.
LLDPE and metallocene LLDPE are hard to extrude at high output. Above a certain shear rate, the film surface turns rough (sharkskin, or melt fracture), deposits build up at the die lip, and the line has to slow down.
Polymer processing aids fix this by coating the die wall so the melt slips through smoothly. For decades the standard PPAs have been fluoropolymers, which belong to the wider PFAS family. Restrictions on PFAS are being developed in the EU and UK, and many brand owners already ask packaging suppliers to confirm PFAS-free materials.
Aviura's PFF grade is a non-fluorinated processing aid for PE and LLDPE film and extrusion. Because non-fluorinated aids can condition the die differently, we recommend a line trial that measures melt fracture clearance, die build-up and output against your current grade before you change the specification.

Melt fracture, die build-up, gels or output: the replacement must fix the same problem.
Compare conditioning time, clearance and output against your current grade.
Ask for a written PFAS-free statement for the grade, not just a product name.
Yes. Conventional PPAs are fluoropolymers, which fall within the broad PFAS definition used in proposed EU and UK restrictions.
For many PE and LLDPE film applications it removes melt fracture and die build-up effectively, but it can behave differently, for example in how long the die takes to condition. That is why we always recommend a line trial.
Yes. A written PFAS-free statement is available for the PFF grade, for your supplier approval file and your customers' audits.
Send us your polymer, process and the problem you want to solve. We recommend a grade and starting let-down, then ship a 1 kg lab sample, 5 kg pilot sample or 25 kg line trial with TDS, SDS and batch COA.
Masterbatch has to prove itself on your extruder, not ours. This is the route every new grade takes.
Polymer, process, the problem to solve, and your current product if you have one.
A grade and a starting let-down for your line, shared with you shortly.
A 1 kg lab sample, 5 kg pilot sample or 25 kg line trial, with TDS, SDS and batch COA.
We review the results with your team and adjust dosage or formulation.
Price, MOQ and lead time fixed against the approved grade.
