Applications Exolit OP 1240 is a flame retardant for thermoplastics and thermosets. Due to its high phosphorus content the product is distinguished by a high efficiency. Exolit OP 1240 was developed especially for the use in polyesters. It is suitable for both glass fibre reinforced and unreinforced grades. The flame
|
|
retarded polyester compounds exhibit very good physical and electrical properties. In PBT, a dosage of 20 % (by wt.) Exolit OP 1240 is usually sufficient to obtain the UL 94 V-0 classification for electrical components (at 1.6 as well as 0.8
|
|
mm thicknesses). In PET, less than 15 % are required to pass UL 94 V-0. Synergistic effects are known with other flame retardants like melamine polyphosphate, melamine cyanurate or zinc borates. Subject to the polymer grade, processing conditions and glass fibre reinforcement the dosage of the flame retardant may vary. Processing Before incorporating Exolit OP 1240, it is important to predry the polyester as usual. If possible, the resulting moisture content should be below 0.05% (by
|
|
wt.) for PBT and 0.005% for PET. Predrying of Exolit OP 1240 is not necessary. However, predrying (e. g. 4h at 120 °C) is recommended, if even very low moisture contents must be avoided. Wear and corrosion protected screw elements are recommended when using Exolit OP 1240 in reinforced polyesters.
