Features & Benefits

Safety-Built Material

Makrolon 6717 achieves UL 94 V-0 flame retardancy at just 2.0 mm thickness, ideal for electrical enclosures or EV components where fire safety is critical.

Unmatched Toughness

With >105% strain at break (ISO 527) and high puncture resistance (65 J at -30°C), it withstands impacts in demanding environments like medical devices or industrial tools.

Processing Flexibility

Branched chain structure ensures smooth flow at 280–320°C melt temps, enabling complex thin-wall molding and reducing cycle times for high-volume production.
