    YIHOO FR960

    Product description FR930 is a phosphorus-based environmentally friendly halogen-free flame retardant, full name diethylphosphinate. This flame retardant is a white powder, organic phosphinate. The product is moisture-proof, insoluble in water and acetone, dichloromethane, butanone, toluene and other organic solvents.
    It is especially suitable for halogen-free flame retardant of high-temperature nylon engineering plastics (6T, 66&PPA, etc.), polyurethane elastomer (TPU), polyester elastomer (TPE-E) and other systems.

    Application FR930 is a flame retardant suitable for thermoplastics and thermosets. It has high phosphorus content, good thermal stability and high flame retardant efficiency.
    Due to the good high temperature stability of FR930, it can be applied to high temperature nylon, suitable for glass fiber reinforced and non-reinforced type. The flame retardant material has good physical and electrical properties.
    In high-temperature nylon, FR930 is used in an amount of approximately 10% (wt) to achieve UL 94 V-0 (1.6 and 0.8 mm thickness). The amount of flame retardant used may vary depending on the polymer, processing conditions, and amount of glass fiber added.
           
    Processing technology Before adding FR930, it is necessary to pre-dry the polymer as usual. If possible, the moisture content of high-temperature nylon should be less than 0.1% by weight, PBT should be less than 0.05% by weight, and PET should be less than 0.005%. Pre-drying of ADP-33 is not required. However, if the system has low moisture content requirements, pre-drying is recommended (e.g. baking at 120°C for 4 h);
    The commonly used mixing and processing method of powder can be used for FR930, and the best dosing method should be determined on a case-by-case basis. It must be ensured that all components are evenly dispersed and that the temperature of the polymer melt does not exceed 350°C.

    Addvantage  Non-hygroscopic, not hydrolyzed and not precipitated
     Suited as flame retardant for thermoplastics and thermosets
     High efficiency due to its high phosphorus content
     UL 94 V-0 rating down to 0.4 mm thickness
     Suited for processing temperatures up to 350 °C
     Suitable for both glass fiber reinforced and unreinforced grades
     The flame retardant polyamide compounds exhibit very good physical and excellent electrical properties
     Suitable for lead free soldering
     Good colorability Non-halogenated flame retardant with favorable environmental and health profile
           
    Application FR930 is suited as flame retardant for thermoplastics and thermosets. Due to its high phosphorus content the product is distinguished by a high efficiency. FR930 can even be applied in high temperature polyamides because of its high temperature stability. It is suitable for both glass fibre reinforced and unreinforced grades. The flame retardant polyamide compounds exhibit very good physical and electrical properties.
    In high temperature polyamides of PA 6T/66 type, a dosage of approx. 15 % (by wt.) FR930 is usually sufficient to obtain the UL 94 V-0 classification for electrical compounds (at 1.6 as well as 0.8 mm thicknesses). Subject to the polymer grade, processing conditions and glass fibre reinforcement the dosage of the flame retardant may vary.
           
    Processing Before incorporating FR930, it is important to predry the polymer as usual. If possible, the resulting moisture content should be below 0.1 % (by wt.) for high temperature polyamides, 0.05 % (by wt.) for PBT and 0.005% for PET. Predrying of FR930 is not necessary. However, predrying (e. g. 4h 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 FR930. 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 350 °C.
