Features & Benefits

Enhanced Sustainability & Compliance

Partially bio-circular and ISCC PLUS-certified, Makrolon® 2456 RE CQ reduces carbon footprint while meeting strict food-contact regulations—ideal for eco-conscious packaging and consumer goods.

Superior Processability

Low viscosity (19 cm³/10 min MVR) enables faster cycle times and easy filling of complex molds. Pre-dried pellets (120°C/2–3 hrs) minimize defects like bubbles or streaks in high-volume injection molding.

Robust Durability

With high impact strength (65 kJ/m² Charpy notched at 23°C) and thermal resilience (HDT 125°C at 1.8 MPa), it withstands drops, heat, and stress in demanding applications like kitchenware or tool housings.
