ExxonMobil Chemica Exxelor VA 1803 Toughening Agent

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.

Features Of ExxonMobil Chemica Exxelor VA 1803 Toughening Agent

  1. Allows polyamides to retain high impact resistance at ultra-low temperatures (down to -40°C).

  2. Enhances polyamide dimensional stability by lowering temperature sensitivity.

  3. Balances stiffness and low-temperature performance in polyamide blends.

  4. Improves impact properties of other engineering thermoplastics (with/without glass fibers/fillers).

Typical Applications Of ExxonMobil Chemica Exxelor VA 1803 Toughening Agent

  1. Used to toughen polyamides for uses needing ultra-low temperature impact resistance (e.g., cold-region engineering parts).

  2. Applied in polyamide-based engineering plastic alloys to optimize low-temperature performance and compatibility.

  3. Utilized in modifying engineering thermoplastics to boost impact resistance across a broad temperature range.
