Used as topical lubricants for over 40 years, perfluoropolyether oils have only recently been introduced as additives for polymers. Bruce Ulissi of DuPont explains how they can provide a number of property enhancements and processing improvements for plastics.
Perfluoropolyether oils (PFPE) are unique materials with a range of molecular weights that have been used as topical lubricants for over 40 years. However, they have only recently been introduced as additives for thermoplastic and thermosetting polymers. Recent development work by DuPont has demonstrated that Fluoroguard® can provide many property enhancements for plastics, some of which are quite unexpected.
PFPE improves wear and coefficient of friction properties at very low levels. Unlike other additives, they have a neutral and in some cases positive effect on the physical properties of the host polymer. Significant processing benefits such as improved mould release and reduced mould deposits from plateout is also standard.
