Excellent heat resistance, strength and toughness, insulation, and oil resistance. It is widely used in automotive parts, electrical and electronic parts.
Polyamide optimized for laser marking
SN series
LEONA™ SN series provides high contrast and clear printing
Laser marking with LEONA™ SN-series resins yields clearer, higher-contrast lettering than typical non-halogen flame-retardant polyamide resins in both of the following situations:
① Forming white letters on black-colored items
② Forming black letters on white, gray, or other light-colored items (including RAL9003 and RAL7035)
Laser marking with LEONA™ SN-series resins can produce clear results for ultra-small letters and symbols.
The following video demonstrates laser marking of a two-dimensional code in an extremely compressed space—side length of just 5 mm—with sufficiently high quality to allow immediate recognition by a cell-phone camera.
Demonstration: Reading a two-dimensional code
LEONA™ SN-series resins yield clear laser-marking results under a wide range of operating conditions.
The figures below show examples of laser-marking results obtained for various combinations of laser power and marking speed. Laser marking with LEONA™ SN-series resins produces clear results even at high marking speeds above 1,000 mm/sec.
These results demonstrate how laser marking with LEONA™ SN-series resins can produce high clarity with excellent performance under a broad range of operating conditions. This capability allows a reduction in the product area required for marking, helping to miniaturize products and increasing product-design freedom.
Moreover, the two-dimensional codes that have recently become increasingly common are more time-consuming than letters to inscribe by laser marking; choosing LEONA™ SN-series resins helps to reduce these marking-time requirements.
