- Product No.:DovaFR PO 313
Function chemicals
DovaFR PO 313 Edition Date May26,2018 Edition Number 2
Halogen-free flame retardant for polyolefin
Product Description
DovaFR PO 313 is a phosphorus-nitrogen compound halogen-free flame retardant with high-efficiency. It is designed for PP, PE, TPV and other polyolefins. DovaFR PO 313 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
l DovaFR PO 313 is a white, odorless, tasteless powder.
l DovaFR PO 313 has high flame retardant efficiency, small addition amount and good dispersion.
l DovaFR PO 313 is good compatibility in polymers and resins.
l DovaFR PO 313 is good thermal stability, thermal decomposition temperature≥260℃.
l Good water resistance, no precipitation, migration, moisture resurgence and water slip phenomenon.
l Superior electrical and mechanical properties.

Applications
DovaFR PO 313 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 313 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.
