Yparex VA 1840

Yparex VA 1840 (formerly known as Exxelor VA 1840) polymer resin is a high flow, 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 1840 polyamide impact modifier is designed to:

  • Modify the impact characteristics of the full range of polyamides for temperatures as low as -20°C (a function of the modifier treat level in the blend).
  • Modify the impact characteristics of other engineering thermoplastics and technical polymers (with or without glass fibres, fillers, etc.).

Key features of Yparex VA 1840 impact modifier

Achieving compatibility between polyolefins and more polar polymers that are capable of interacting with maleic anhydride.

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 1840 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. This can be achieved easily because of the low viscosity of the product. 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.
