DovaFR ADP 330
Organic phosphinate (ADP) used in HT PA(PPA)
DovaFR ADP 330 is an excellent flame retardant for application in engineering plastics such as polyamides, polyesters, thermosets and elastomers. It is a halogen-free flame retardant based on organic phosphinates, white powder. DovaFR ADP 330 is not hygroscopic and is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene and etc.
- DovaFR ADP 330 can reach UL 94 V-0 rating down to 0.4 mm thickness.
- DovaFR ADP 330 has high flame retardant efficiency, small addition amount and good dispersion.
- The processing temperature of DovaFR ADP 330 can be up to 365 °C.
- Good physical and electrical properties.
- Low density, smoke and toxicity.
- Good water resistance, no precipitation, migration, moisture resurgence and water slip phenomenon.

²) Technical data: The technical data are used solely to describe the product and are not subject to regular monitoring.
DovaFR ADP 330 is considerable non-halogen flame retardant, which can be used as a halogen-free flame retardant for polyamides, polyesters, thermoset resins in electrical engineering and electronics (E&E) applications for switches, plugs, PC fans, and structural and housing components. It is suited for both glass-fiber-reinforced and unreinforced grades with good mechanical and electrical properties.
In high temperature polyamides of PA 6T/66 type, a dosage of approx. 12 % (by wt.) ADP-330 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 fiber reinforcement the dosage of the flame retardant may vary.
Processing
Before incorporating ADP-331, 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. Pre-drying of ADP-331 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 ADP-331. 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.
