Product Description

PNPO is a Halogen-Free Flame Retardant, which develops its effectiveness through phosphorus/nitrogen synergism.

When incorporated into polyolefine, it shows high processing stability and no migration. PNPO differs in its mode

of action from halogenated flame retardants in the fire. When the polyolefine on exposure to flame, the carbon foam

layer formed protects the polymer through its heat insulating effect to reduce further oxygen access and prevent dripping of

the polymer. At the same time there are no halogen hydride gases to cause.

Recommended dosage:






















Tips: Oxide index reach 34% with dosage 25% in PP

Passing GWIT 850℃(3.0mm) testing with dosage 30% in PP


It can mostly used in a range of thermoplastics,rubber,resin, especially PP, PE, EVA, TPE, etc., which is suitable extrusion and injection moulding applications.

The Flame Retardant property can reach UL94 V-0 Level.

Processing instruction:

1. The twin-screw extruder`s processing temperature should not be too high(below 230 ℃ ).

Meanwhile, we should maintain a certain vacuum in order to make the material more stable.

2. Choosing proper matrix resin according to MFR

3. Choosing proper filler and control dosage .Normally ,the filler will reduct Flame retardant efficiency.

4. PNPO don`t contain Anti-dropping agent . Customer need to choose proper anti-dropping agent as required.

5. 0.1-0.5% of anti-oxidant is recommended to use together with PNPO.

Package & Storage:

Net weight 25KG Kraft bag with PE liner.

It is not dangerous cargo .You should handle the material according to the instruction described on MSDS.The MSDS is available from sales department once required.Our regular mark is printed on the surface of package in advance .You should inform our sales person in advance If you don`t need this or have any special demand for mark.
