Product Introduction of the B1A

B1A is a chemically functionalized polypropylene with high content of maleic anhydride. Grafted maleic anhydride brings polarity to base polymer and outstanding bond character on different fillers, such as glass fiber, mineral filler or natural fibres.
It could be used as compatibilizer for Polypropylene and Polyamide to make PP/PA blends. It could also be used as a coupling agent for glass fiber reinforced Polypropylene, or called PP/GF composites. The high MFR of B1A could ensure the coupling agent with a good fluidity during the process in twin-screw extruder.

B1A is propene polymer with functionalized maleic anhydride,which is especially suitable for the reinforcing and compatibilizing of PP mineral fiber and glass fiber.


1. Be used as the PP interface modifier for glass fiber reinforcing and mineral filling to increase the tensile strenth and bending strength.
2. Be used as PA/PP or PA/PE alloy compatibilizer.
3. It can be used as a compatibilizer between inorganic reinforcing materials (glass fiber) and filling materials (calcium carbonate, talc, etc.) and PP;
4. Can be used as PP extrusion sheet / plate surface improver, can effectively improve the material surface level up degree, eliminate material surface concave and convex and pitting;
5. Can be used as a compatibilizer for PP / nylon alloy:
6. Can be used as wood-plastic compatibilizer;
7.  It can be used to improve the adhesion of PP to polar materials (metal, nylon, etc.).
