PolyVivo Packaging Desiccant

Previously PolyVivo polymers had been packed with standard silica gel desiccant which is perfectly functional to remove moisture but does not indicate when it is expired. In order to provide a desiccant which both maintains package dryness and indicates quality PST is now packaging with DrieRite dessicant in small punctured vials. The blue color indicates that the dessicant is still active and providing a dry environment to protect your polymer.  Vials are also screw-cap so you can empty and re-use the dessicant as desired.
