Lushan PR-3

Maleic anhydride grafted polypropylene. Lushan PR-3 by Guangzhou Lushan New Materials acts as adhesion promoter and coupling agent. It 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. At the same time, the introduction of polypropylene molecular chain polar groups could significantly improve PP's shading ability. 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%), Lushan PR-3 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. As compatibilizer for PA/PP, PA/PE alloy: to improve the processing of nylon, impact resistance, lower water absorption and products dimensional stability. Possesses high grafting ration with wide application range.
