Yparex VA 1801

Yparex VA 1801 polymer resin (formerly known as Exxelor VA 1801) is a medium viscosity, semi- crystalline ethylene copolymer functionalized with maleic anhydride by reactive extrusion. Its fully saturated backbone results in outstanding thermal and oxidative stability leading to enhanced weatherability. Moreover, its elastomeric nature provides high impact resistance at room temperature and at low temperature when blended with engineering polymers such as polyamide.

Yparex VA 1801 is designed to:

  • Modify the impact characteristics of other engineering thermoplastics and technical polymers (with or without glass fibres, fillers, etc.).
  • Achieve compatibility between polyolefins and more polar polymers that are capable of interacting with maleic anhydride.

Key features of Yparex VA 1801

Performance enhancements in polyamide:

  • Outstanding notched Izod impact resistance at room temperature.
  • Very high notched Izod impact resistance down to -20°C.
  • Improved flexibility.
  • Reduced moisture sensitivity and improved dimensional stability allowing the production of molded parts with different wall thickness.
  • Improved assembly of freshly molded parts.
  • Increased impact resistance of glass-reinforced compositions.

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 free-flowing pellets normally packed in 25 kg bags (50 bags per pallet), 450 kg octabins or 1 ton supersacks.

Processing statement

Yparex VA 1801 resin can be added to polyamide to achieve optimum dispersion within the polymer matrix(average particle size below 1 micron) in order to obtain the best performance. Compounding parameters that can lead to optimized performance include extruder type, screw design, barrel temperature, screw speed, throughput and residence time. Our experienced technical service engineers and chemists are always on hand to help you in achieving the best performance from your processing and compounding operations.
