PRODUCT DESCRIPTION
Exolit AP 760 is a non-halogenated flame retardant based on Exolit AP 422, which develops its effectiveness throughphosphorus / nitrogen synergism. When incorporated into thermoplastics, it exhibits high processing stability. Exolit AP 760 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The thermoplastic material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect, reduces further oxygen access and prevents dripping of the thermoplastic.
APPLICATIONS
Exolit AP 760 may be used in poly-propylene, PP-copolymers and PP-blends. The application areas are nearly the same as for Exolit AP 750.Compared to Exolit AP 750, Exolit AP 760 shows an improved thermal stability, which allows an approx. 30°C larger processing window. In compounding of Exolit AP 760, a reduced water uptake, less contamination of the water bath and less soapiness of the polymer strength is observed.
