Exxelor VA 1840 is a high-flow, semi-crystalline ethylene copolymer functionalized with maleic anhydride, made via reactive extrusion. Its fully saturated main chain offers excellent thermal and oxidative stability, boosting polyamide impact resistance at both room and low temperatures (down to -20°C). It also enhances compatibility between polyolefins and polar polymers, suiting engineering plastic modification.
Improves polyamide notched impact performance at room and low (-20°C) temperatures.
Lessens polyamide moisture sensitivity, enhancing dimensional stability.
Increases flexibility and assembly performance of molded polyamide parts.
Enhances compatibility between polyolefins and polar engineering polymers.
Used to toughen polyamides, boosting impact resistance across a wide temperature range (-20°C to room temperature).
Applied in polyamide-based engineering plastic alloys to improve compatibility and overall performance.
Utilized in modifying other engineering thermoplastics (with or without glass fibers/fillers) to enhance impact characteristics.
