Engineering plastics modification

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.

New Orevac® Impact Modifier grades for polyamide

Orevac® IM300/IM300N and IM800 new grades have been formulated to speed up the manufacturing productivity of these compounds while maintaining excellent impact resistance and mechanical properties.

 

Orevac® IM300/IM300N 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/IM300N and IM800 complete Arkema’s range of reactive polymers with the Lotader® 4700 resin, already used for the modification of polyamides.
