Arkema completes its reactive polyolefins range with two grades to fine-tune compounds properties

- Press release
Lotader® AX resins are widely used as reactive agents to improve the processability as well as the impact resistance of thermoplastic polyesters (PET/PBT), polyphenylene sulfide (PPS) compounds. They also increase the rutting resistance of polymeric modified road pavements. Two new grades, Lotader® AX8750 and AX8930 copolymers, have been designed to complete Arkema’s range of impact modifiers and/or compatibilizers, which enables processors to play, depending on the dosage, on various properties of the compounds: fluidity in processing, impact resistance and mechanical strength.
Food tray

The Lotader® resins are a unique range of reactive ethylene copolymers, functionalized with anhydride or epoxide groups. These products combine the processability of low density polyethylene and the reactivity necessary for compatibility with engineering resins.

The Lotader® AX terpolymers meet the need to flexibilize engineering plastics such as polyamides, thermoplastic polyesters, and polysulfones.

Lotader® AX8750 and AX8930 new grades have been formulated to speed up the manufacturing productivity of these compounds while maintaining excellent impact resistance and mechanical properties.

Automotive engine


Lotader® AX8750 is a brand new chemistry since this new terpolymer is made of ethylene, butyl acrylate and glycidyl methacrylate. Thanks to its high fluidity, it opens up new opportunities in terms of processability of the compounds.

Its low temperature performance targets frozen food packaging and automotive compounds.


Lotader® AX8930 reactive terpolymer has been designed to achieve good impact resistance while maintaining fluidity. It is therefore recommended for applications where the final compounds needs to be injection molded.


Lotader® AX8930 and AX8750 terpolymers complete Arkema’s range of reactive terpolymers, Lotader® AX8900, AX8820 and AX8840 resins, already used for the modification of polymers such as thermoplastic polyesters (PET/PBT), polyphenylene sulfide (PPS), as well as for bitumen modification.
