Product Description

Product Description

DovaFR PO 313S 

Halogen-free flame retardant for polyolefin

DovaFR PO 313S is a phosphorus-nitrogen compound halogen-free flame retardant with high-efficiency. It is designed for PP, PE, TPV and other polyolefins. DovaFR PO 313S is based on Nitrogen and phosphorus (ammonium polyphosphate APP free). It mainly plays a flame-retardant effect with char-forming and expansion flame-retardant mechanism. Applied to RoHS and REACH regulations.

Benefits

1. DovaFR PO 313S is a white, odorless, tasteless powder.

2. DovaFR PO 313S has high flame retardant efficiency, small addition amount and good dispersion.

3. DovaFR PO 313S is good compatibility in polymers and resins.

4. DovaFR PO 313S is good thermal stability, thermal decomposition temperature≥260ºC.

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

6. Superior electrical and mechanical properties.

Applications

DovaFR PO 313S is used as flame retardant in oily polyurethane, oily acrylic, silicone and other adhesives. It can be directly coated with PET/Smooth substrates such as aluminum foil without graininess. Flame retardant performance can reach UL94V-0 level. In TPE, TPU and other elastomer products, is resistant to white oil, does not precipitate, and has little effect on physical properties.

Processing considerations

In air, the initial thermal decomposition temperature of DovaFR PO 313S is 280℃. The processing temperature of the screw can be adjusted to strengthen the dispersion and improve the effect of plasticization according to the specific situation. A certain degree of hollowness must be maintained during the process of screw extrusion. In PP, it is not recommended to use strong shear screw combinations.
