Transparent, low-flammability, UV-resistant film made from a crystallizable thermoplastic and process for its production

摘要

A transparent, flame retardant, UV stable, oriented film (I) comprises a crystallizable thermoplastic of 5-300 microns in thickness and contains a UV stabilizer and a flame retardant whereby at least the flame retardant is dosed into the thermoplastic as a master batch at the production of the film. An Independent claim is included for the production of the film (I) by extrusion whereby the flame retardant, optionally together with the hydrolysis stabilizer is added by means of masterbatch technology such that the flame retardant is fully dispersed in a solid matrix such as the thermoplastic itself, polyethylene terephthalate or another compatible polymer.
