Yparex 41430 polymer resin - The Compound Company

Yparex 41430

Yparex 41430 polymer resin is a maleic anhydride functionalized polypropylene homopolymer, produced by reactive extrusion. It has been primarily designed to add polarity to polypropylene matrices and in particular to improve polypropylene reactivity with amino-silane treated glass reinforcements. Its high content of maleic anhydride allows its use at low treat levels while maintaining optimum application properties.

The grade is designed for:

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.

Key Features:

Performance enhancements in glass-filled polypropylene:

Improved cost/performance balance compared to earlier generation modifiers.

Easy moulding 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.

Storage and handling

Comprehensive material safety data sheets are provided to recommend safe practices during usage. For easy handling and storage, this grade is supplied as f ree-flowing pellets normally packed in 20 kg bags (65 bags per pallet) or 500 kg boxes. Please store Yparex under dry conditions in the original packaging, protected from UV light. In practice, the shelf-life will often be longer.
