Lushan Maleic anhydride grafted polypropylene (PP-g- MAH)  is evaluated as compatibilizer which is used to fill or reinforce polypropylene. As the polymer coupling agent, it can significantly improve the filled or enhanced PP's mechanical properties and heat resistance. The introduction of polypropylene molecular chain polar groups also significantly improved PPs shading ability.

Compatiblizer Usage

1,     As compatibilizer for polypropylene filled with glass fiber or mineral: maleic anhydride grafted polypropylene has a high polarity. As long as adding a small amount (4%), it can significantly improve interface bonding strength between PP and the glass fiber, talc, mica and other inorganic fillers. Modified polypropylene's tensile strength, bending strength and impact strength have been improved significantly.

2,      As compatibilizer for PA / PP, PA / PE alloy: to improve the processing of nylon, impact resistance, lower water absorption and products dimensional stability.

3,   Improve coating and painting properties for polypropylene.
