LOTADER® 4720

LOTADER® 4720 is a random ethylene-ethyl acrylate-maleic anhydride terpolymer. Acrylic ester brings softness and polarity, while keeping high thermal stability during processing. The high content of acrylic ester leads to high flexibility (low-crystallinity) and high impact absorption behavior. Maleic anhydride provides reactivity (towards OH and NH2 groups), leading to optimal dispersion during melt mixing with engineering thermoplastics. LOTADER® 4720 is suitable as modifier to improve the impact strength of polyamides (PA6,PA66, PA12...). It can also be used as a compatibiliser for polyamides/polyolefins blends.

Processing Information

Heat stability of acrylate comonomer allows processing temperatures as high as for polyamides. However, to minimize the generation of gels, it is recommended to purge the equipment with LDPE after a run is completed. LOTADER® 4720 is not corrosive.

Storage & Handling

Storage and Shelf Life Conditions
  • LOTADER® 4720 is usually packed in waterproof bags or rigid containers with waterproof liner. It should be stored in dry conditions and be kept out of moisture in an aerated building.
  • Improper storage conditions may cause degradation and could have consequences on physical properties of the product. It is recommended to reseal the bag or the liner after use to protect LOTADER® 4720 against moisture.
  • Shelf life is three years from the date of delivery, in unopened packaging.
