Exxelor PO 1015 polymer resin is a maleic anhydride functionalized polypropylene copolymer, produced by reactive extrusion. It has been primarily designed to add polarity to polypropylene matrices and in particular improve polypropylene reactivity with amino-silane treated glass reinforcements.

This grade is designed to:
- Function as a coupling agent between reinforcing materials, such as glass fibers and inorganic fillers, and polypropylene.
- Achieve compatibility in polypropylene/polyamide alloys.
- Achieve compatibility between polyolefins and more polar polymers that are capable of interacting with maleic anhydride for alloying, recycling or co-extrusion purposes.
- Improve polypropylene-to-metal adhesion properties.
