Product Introduction
Copolymerized PP Efficient Flame Retardant WH-002
Main Features
1.Compared with the traditional octabromoether and octabromosyl S ether,antimony trioxide is not needed to be added,and the bromine content is low.When the addition of 2.0-4.0%of copolymernized PP with high ethylene content,the flame retardant grade can reach UL94 V-2 level;
2.It can be filled with 10-20%talc powder,barium sulfate and other inorganic fillers
3.The flame retardant PP prepared by this product is baked at 70-80℃ for 300 hours without precipitation of surface flame retardants,resistance to migration,and good light and heat stability;
4.Meet the requirements of IEC60695-2-13 GWIT775℃(3.0mm)and IEC60695-2-12 GWFI 960℃ (3.0mm):
5.The flame retardant PP prepared with this product meets the requirements of SGS and REACH.

Flame Retardant Property
1.No precipitation:70-80℃ baking 300 hours surface flame retardant no precipitation;
2.Meet the requirements of IEC60695-2-13 GWIT775°C(3.0mm)and IEC60695-2-12 GWF¹960°C (3.0mm).
3.It can solve the curent situation that the low added amount of flame retardants in the market can not be applied to homopolymenization,copolymenization PP and filled PP system at the same time;
4.It can meet the requirements of high temperature themmal aging,and the elongation does not decrease significanty at 130℃ and 1000 hours,and the impad maintains a small change.
Processing Precautions
1.Avoid adding calcium carbonate filler,which is unfavorable to flame retardant performance;
2.the equipment must ensure accurate temperature control,to avoid the equipment due to temperature ontrol is not allowed to local overheating caused by flame retardants play a role in advance and reduce the physical properties of the material phenomenon,it is recommended that the processing temperature setting range is:170-170-170-170-180-180-180°C;
3.In order to ensure unifom mixing,it is best to add a small amount of polypropylene powder in the formu a to ensure uniform refuelling and achieve better dispersion effect;
4.The screw combination uses weak shear type to avoid material degradation caused by too strong shear
