Glass Bead with Refractive Index 1.93Nd
1.93nd glass bead is used for “Exposed-Lens” type retro-reflective articles (e.g., open-type reflective sheets, reflective fabric. reflective tape, reflective yarn) and “Encapsulated-Lens” type retro-reflective articles (e.g., high intensity grade reflective sheet). It can also be used for reflective ink, paint and in the fields of personal security and protective products.
