Features & Benefits

Reliable Flame Resistance

Makrolon 6485 delivers UL 94 V-0/5VA ratings, critical for electronics and automotive parts exposed to high heat or electrical risks, ensuring compliance without secondary treatments.

Optimized Processing Efficiency

Medium viscosity (9.0 cm³/10 min MVR) and easy-release properties reduce cycle times and mold fouling, cutting production costs for complex components like connectors or housings.

Tough Mechanical Performance

High impact strength (>50% nominal strain) and dimensional stability (0.6–0.8% shrinkage) guarantee durable parts that withstand drops, vibrations, and thermal shifts in harsh environments.
