Exxelor PO 1020Maleic anhydride functionalized polypropylene

Product description

Exxelor PO 1020 is a high performance maleic anhydride functionalized homopolypropylene produced byreactive extrusion. It has been primarily designed to add polarity to polypropylene matrices and in particular toimprove polypropylene reactivity with amino-silane treated glass reinforcements. Its high content of maleicanhydride allows its use at low treat levels while maintaining optimum application properties.

Applications

Exxelor PO 1020 is designed to:

• Function as a coupling agent between reinforcing materials, such as glass fibers and inorganic fillers, andpolypropylene.

• Achieve compatibility in polypropylene/polyamide blends.• 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.

Performance enhancements in glass-filled polypropylene include:

• Improved cost/performance balance compared to earlier generation modifiers• Easy molding of highly glass filled compounds and/or complex and thin parts due to its high flow properties• Outstanding unnotched Izod and Charpy impact performance• Excellent notched Izod and Charpy impact resistance• Improved tensile and flexural strength

Processing

Exxelor PO 1020 can be added to polypropylene to achieve optimum dispersion within the glass-reinforcedmatrix in order to obtain the best performance. Compounding parameters that can lead to an optimizedperformance include extruder type, screw design, barrel temperature, screw speed, throughput, residence timeand material feeding 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 1020 issupplied as free-flowing pellets normally packed in25 kg bags (50 bags per pallet) or 1 ton supersacks.
