Flame-resistant Polyester Film
 1. COMPOSITION AND PRESENTATION FW-6023(V2) is a kind of biaxial oriented and uniform yellowish polyester film which consists of polyethylene terephthalate chip and corresponding additive. The film is contains an environmental protective flame retardant as additive, which has flame resistance and release less poisonous gas compared with general haloids flame retardant.
The product with high flame resistance grade which meet 94VTM-2.
2. PROPERTIES AND APPLICATIONS
Properties: the film exhibits excellent electrical properties, excellent physical and mechanical properties, low thickness tolerance and low shrinkage. It have low thickness tolerance, good flame resistance.
Applications: the film free of flame retardant separated out under the long-term working condition, free of pollution of the environment. It Is suitable for use in electric motor and electric apparatus, building and decorating material, heating system which require high safety.
