Key takeaways about PARALOID™ EXL-2691J Impact Modifier

• Low temperature toughness: PC formulations with 5phr PARALOID™ EXL 2691J retain >80% impact strength even at −40°C; unmodified PC fails under these conditions.

• Hydrolysis resistance: Retains ~80% of original impact strength after 1,200h hydrolytic heat aging.

• Improves hydrolysis durability in PC with up to 75% recycled content

• Processing stability: Maintains high impact strength even at 320°C injection molding conditions.

• Stabilizes impact strength across multiple PCR PC sources

• Shifts failure mode from complete break to hinge break, clear sign of improved toughness
