Greener Solutions 2020: PFAS in Aftermarket Carpet Treatments

The aftermarket carpet treatment team presented PFAS alternatives for aftermarket stain repellant treatments. Their proposed solutions included natural waxes and oils, biopolymers, and silicon-based materials, including silicon dioxide nanoparticles and silicon-containing small molecules and polymers. The team identified chitosan and cellulose nanocrystal as candidates for a biopolymer approach. The team noted the potential to combine multiple strategies to achieve optimal performance metrics.
