Description:
MIXROY 340 is a white, fine-grained powder based on an organic phosphinate. The product is non-hygroscopic and it is insoluble in water and organic solvents.
Applications:
MIXROY 340 is a flame retardant for thermoplastics and thermosets. Due to its high phosphorus content the product is distinguished by a high efficiency.
MIXROY 340 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.) MIXROY 340 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.
GUIDANCE FOR USE
Before incorporating MIXROY 340, 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 MIXROY 340 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 MIXROY 340 in reinforced polyesters.
The mixing and processing methods customary in powder processing of polymers can be used with MIXROY 340. The VDI Guideline 2263 “Prevention of dust fires and dust explosions” or the relevant national regulations must be observed. The optimum conditions for incorporating should be determined in each individual case. Care must be taken to ensure homogeneous dispersion of all components. The temperature of the polymer melt should not exceed 320 °C.
