halogen free flame retardant for PP PE polyolefins

PRODUCT DETAILS

 


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.

 

 

Benefits

Shows high processing stability in contrast to similar competitive material

Particularly effective in thermoplastic polyolefins (e. g. polyolefin hotmelts),

urethanes (e. g. integral skin foams, rigid foams, sealants), and epoxy resins

(adhesives, sealants, structural laminates, gelcoats)

Positive secondary fire effects such as low smoke density, lower formation of toxic

smoke or corrosive gases

Non-halogenated flame retardant with favorable environmental and health profile

Processing instruction:

1.  The optimum conditions for incorporating should be determined in each individual case. Care must be taken to ensure homogeneous dispersion of all components.

2.Both single- and twin-screw extruders are suitable for incorporating the product. The temperature of the polymer melt should not exceed 230°C.

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

4.When a water bath is used for cooling the strands, it is advisable to keep the passage through the water bath as short as possible to permit optimum evaporation of any entrained water.

 

 

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 SDS.

Minimum shelf life is 12 months stored in a dry and ventilated warehouse.
