2 Density (g/cm3 0.90
3 Melt flow rate g/10min  100
4 Grafting rate% 0.6-0.8


Scope of use:

Used as an interfacial modifier for glass fiber and mineral filled PP: maleic anhydride grafted PP gives PP polarity and adhesiveness, which can greatly improve the interfacial bonding force between PP and glass fiber, talc, mica and other inorganic fillers, and significantly improve the tensile strength, bending strength and impact strength of modified PP.

Used as a compatibilizer for PP and resin alloys containing graded groups: maleic anhydride grafted PP can be used as a compatibilizer for PA/PP and PA/PE blend alloys to improve the processability and impact resistance of nylon, reduce water absorption and improve the dimensional stability of products.

Giving PP coatability and paintability: improving the coatability and paintability of PP.

Method of use:

Proportionally granulated by twin-screw extrusion.

Reference proportioning quantity:

Users according to the requirements and cost-effective as appropriate to add.


25kg package, stored in a ventilated and dry place, not more than 24 months from the date of production.
