Amorphous, white, UV-stable thermoformable film, useful in interior or exterior applications, formed from crystallizable resin, e.g. polyester, contains white pigment and soluble flame retardant and UV stabilizer

摘要

An amorphous, white, non-flammable, UV-stable thermoformable film, having thickness 30-1000 mu m containing a crystallizable thermoplastic resin (I) as main component, additionally contains (A) at least one white pigment, (B) at least one flame retardant which is soluble in (I) and (C) at least one soluble UV-stabilizer. An Independent claim is included for production of the film, by mixing (I) with (A) and a precrystallized and/or predried masterbatch containing (I), (B) and (C), forming a molten film from the mixture by extrusion, taking up the film on a drawing off roller and solidifying to an amorphous film.
