EXXELOR™Modifiers for Technical Polymers

Exxelor PO 1015Maleic anhydride functionalized polypropylene

Product description

Exxelor PO 1015 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 polypropylenereactivity with amino-silane treated glass reinforcements.

Applications

Exxelor PO 1015 is designed to:

• Function as a coupling agent betweenreinforcing materials, such as glass fibers andinorganic fillers, and polypropylene.

• Achieve compatibility in polypropylene/poly-amide alloys.

• Achieve compatibility between polyolefins andmore polar polymers that are capable ofinteracting with maleic anhydride for alloying,recycling or co-extrusion purposes.

• Improve polypropylene-to-metal adhesionproperties.

Performance enhancements in glass-filled polypropylene include:

• Outstanding unnotched Izod and Charpy impact performance.• Excellent notched Izod and Charpy impact resistance.• Improved tensile and flexural strength.

Processing

Exxelor PO 1015 can be added to polypropylene, to achieve optimum dispersion within the glass-reinforcedmatrix and achieve the best performance. Compounding parameters that can lead to optimized performanceinclude extruder type, screw design, barrel temperature, screw speed, throughput, residence time and materialfeeding sequence.

Our experienced technical service engineers and chemists are always on hand to help you in achieving the bestperformance from your processing and compounding operations.

Storage and handling

Comprehensive material safety data sheets areprovided to recommend safe practices during usage.For easy handling and storage, Exxelor PO 1015 issupplied as free-flowing pellets normally packed in 25kg bags (50 bags per pallet) or 1 ton supersacks.
