Key Features & Applications

High Fluidity: With MFI of 35g/10min (220°C/10kg), KF-740 easily fills long flow paths and complex geometries, making it ideal for thin-wall injection molding.
Dimensional Stability: Low and uniform shrinkage ensures tight tolerances for assembled parts.
Balanced Toughness: Notched impact strength of 20 kJ/m² provides good resistance against everyday impacts.
Easy Coloring: Can be colored to meet various aesthetic requirements.

Typical Applications:

Office equipment enclosures (printers, copiers)
Large home appliance parts (TV backs, vacuum cleaners)
Thin-wall containers & toys
Electronic housing requiring HB rating
