Exolit® OP 1230

Highly stable phosphinate flame retardant

Edition Date :
August 19, 2021
Exolit OP 1230 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. Clariant’s Exolit OP flame retardants for polyamides are all based on aluminum diethyl-phosphinate (= DEPAL). The pure substance DEPAL is sold as Exolit OP 1230 and in combination with synergists as Exolit OP 13xx types. Exolit OP 1230 is the first non-halogenated flame retardant which can withstand the demanding requirements of this high end segment of engineering plastics.

Applications

Exolit OP 1230 is suited as flame retardant for thermoplastics and thermosets. Due to its high phosphorus content the product is distinguished by a high efficiency.

Exolit OP 1230 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.) Exolit OP 1230 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 Exolit OP 1230, 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 Exolit OP 1230 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 materials are recommended for compounding and injection-molding of Exolit OP 1230 in reinforced polyesters, high temperature polyamides, or aromatic polyamides.

The mixing and processing methods customary in powder processing of polymers can be used with Exolit OP 1230.

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 330 °C.
