The index of refraction, shown here for Asaflex™ and other clear resins,
is a basic guide to the transparency of the blended resins. |

Refractive
index of Asaflex™ and other clear polymers
Maximum transparency can generally be obtained by selecting resins with mutually similar indexes of refraction.
Those of Asaflex™ and SC, as shown here, provide a particularly close match.
