Aluminum Diethyl Phosphinate (ADP) Used in High Temp. Nylon PA Op1230/1240

Product Description

DovaFR ADP 331

Organic phosphinate (ADP) used in high temp. Nylon,PA,PBT,PET

Product Description

DovaFR ADP 331is an excellent flame retardant for use 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 331 is not hygroscopic and is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene and etc.

Benefits
 
1. DovaFR ADP 331 can reach UL 94 V-0 rating down to 0.4 mm thickness.

2. DovaFR ADP 331 has high flame retardant efficiency, small addition amount and good dispersion.

3. The processing temperature of DovaFR ADP 331 can be up to 350 °C.

4. Good physical and electrical properties.

5. Low density, smoke and toxicity.

6. Suitable for both glass fiber reinforced and unreinforced grades.

7. Good water resistance, no precipitation, migration, moisture resurgence and water slip phenomenon.

8. Good colorability, non-halogenated flame retardant with favorable environmental and health profile.

Applications

DovaFR ADP 331 is considerable non-halogen flame retardant, which is suited as flame retardant for thermoplastics and thermosets. Due to its high phosphorus content the product is distinguished by a high efficiency. ADP-331 can even be applied in high temperature polyamides because of its high temperature stability. It is suitable for both glass fiber reinforced and unreinforced grades. The flame retardant polyamide compounds exhibit very good physical and electrical proper.

Recommended dosage

Recommended dosage
In high temperature polyamides of PA 6T/66 type, a dosage of approx. 15 % (by wt.) ADP-33 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.
