NEOFLON™ FEP NP-40

Technical Datasheet | Supplied by Daikin
NEOFLON™ FEP NP-40 by Daikin is a perfluoroethylene propylene (FEP) copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). Exhibits superior stress crack resistance, low melt viscosity, high performance, high transparency, resistance to weather-, chemicals-, moisture-, light-, flame- and permeation. Shows non-sticking properties, electrical reliability, low reactivity, low critical surface energy, chemical- and thermal stability. Possesses low dielectric constant, dissipation factor with high dielectric strength over a wide range of frequencies and temperatures. Suitable for compression molding, injection molding and extrusion processes. Recommended for films, sheets, tubes, sleeves, pipe- and valve linings. NEOFLON™ FEP NP-40 complies with FDA 21 CFR.177.1550, ISO 9001 (Quality System), ISO 14001 (Environmental System) and Responsible Care 14001 (Safety, Health, Environment and Security).
