Description:
MIXROY 950 is a white granular powder based on an organic phosphinate. The product is not hygroscopic and slightly soluble both in water and in common organic solvents.
Applications:
MIXROY 1050 is a flame retardant for thermoplastics and synthetic fibers. Due to its high phosphorus content the product is distinguished by a high efficiency. MIXROY 1050 was developed especially for the use in polyesters. It is suitable for injection moulding and fibre applications. The flame retarded polyester compounds exhibit very good physical and electrical properties. The recommended dosage of MIXROY 1050 for PET fibers is 5-10 %. With 5% MIXROY 1050 a limit oxygen index (LOI) of 33 % can be achieved. MIXROY 1050 has to be incorporated in the PET compound before the spinning process. In PBT, a dosage of 10-15% (by wt.) MIXROY 1050 together with 10-15% nitrogen synergists like melamine polyphosphate or melamine cyanurate 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 flame retardant is required to pass UL 94 V-0.
GUIDANCE FOR USE
Subject to the polymer grade, processing conditions and glass fibre reinforcement the dosage of the flame retardant may vary.
MIXROY 1050 melts under processing temperatures above 200 °C and is miscible with the molten polyesters. Before incorporating MIXROY 1050, it is important to pre dry 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 1050 is not necessary. However, predrying (e.g. 4 h at 120 °C) is recommended, if even very low moisture contents must be avoided. The mixing and processing methods customary in powder processing of polymers can be used with MIXROY 1050.
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 300 °C.
