Polymer Modifiers Orevac IM
Impact Modifiers for Polyamide Compounds
Arkema’s range of polymer modifiers including reactive terpolymers and grafted polymers are widely used to improve the impact strength as well as the fluidity of polyamide (PA) compounds. Two new grades, Orevac IM300 and IM800 grafted polymers, have been designed to complete Arkema’s range of impact modifiers which enables processors to play on various properties depending on the loading: fluidity in processing, impact resistance and mechanical strength of PA compounds.
The Orevac resins are a unique range of reactive polymers due the grafting of anhydride groups. These products combine an outstanding the processability and the required reactivity with polyamides. The Orevac® IM grafted polymers meet the need to flexibilize engineering plastics such as polyamides. Orevac IM300 has been designed to combine an excellent fluidity with high impact resistance at room temperature. Thanks to its high fluidity, it opens up new opportunities in terms of processability of the compounds such as injection molding of small pieces with specific geometries or glass-reinforced PA. Orevac IM800 grafted polymer has been designed to achieve excellent impact resistance at low temperature such as -40°C with a very low ductile/brittle transition temperature. It is therefore recommended for specific automotive applications.
Orevac IM300 and IM800 complete Arkema’s range of reactive polymers with the Lotader 4700 resin, already used for the modification of polyamides. The two new Orevac grades are now available commercially globally through Arkema’s local subsidiary and distribution network. They are produced in USA to be closer to the American market.
