Tekra (a division of EIS Inc.) has achieved a new level of fire performance for polymer films, offering halogen-free VTM-0 fire performance with Tetoron® UF polyethylene terephthalate (PET) films and Teonex® QF polyethylene napthalate (PEN) films.
Both products are based on PIN flame retardants and combine chemical resistance, high tensile strength, dielectric properties and high quality white coloration (>90 diffuse reflectance across the visible light spectrum). Teonex® QF PEN can withstand processing temperatures up to 180°C. Both products available in thickness 25 to 250 microns and are adapted for applications including insulating materials and labels in electronics and batteries, flexible circuitry and lighting, offering more cost effective performance solutions than polyimide or polyester films currently on the market.
