LED performance depends on heat removal and optical control. Small material defects quickly show up as brightness loss or visual defects.
Industry Problems with Conventional Grades
Junction temperature rise reducing lifetime
Light leakage reducing contrast
Visible coating defects
Color and brightness drift over time
How iSTAR solutions are used
NITRAXA®
Used in thermal paths to keep LED junction temperatures under control.
SPHEREXA®
Used in optical masking and light-control areas to block stray light and improve contrast.
ASPIREXA®
Ensures smooth, defect-free processing in coatings and compounds used in LED assemblies.
