Exxelor VA 1803 is a high-flow, amorphous maleic anhydride-functionalized ethylene copolymer made via reactive extrusion. Its fully saturated main chain ensures excellent thermal and oxidative stability, letting polyamides keep impact resistance even at -40°C. It also boosts compatibility between polyolefins and polar polymers, fitting engineering plastic modification.
Allows polyamides to retain high impact resistance at ultra-low temperatures (down to -40°C).
Enhances polyamide dimensional stability by lowering temperature sensitivity.
Balances stiffness and low-temperature performance in polyamide blends.
Improves impact properties of other engineering thermoplastics (with/without glass fibers/fillers).
Used to toughen polyamides for uses needing ultra-low temperature impact resistance (e.g., cold-region engineering parts).
Applied in polyamide-based engineering plastic alloys to optimize low-temperature performance and compatibility.
Utilized in modifying engineering thermoplastics to boost impact resistance across a broad temperature range.
