DuPont Packaging & Industrial Polymers, Wilmington, Del., has introduced two new grades of Selar PA amorphous nylon for use as a high-barrier resin in containers for nail polish and waterproof mascara. New Selar PA 3426R for nail-polish containers provides superior transparency plus barrier to water vapor, oxygen, carbon dioxide, solvents, and essential oils. New impact-modified Selar PA 7003 for waterproof mascara tubes provides increased drop-impact resistance and processability to high gas barrier, chemical resistance, scratch resistance, and gloss.
