— 1:1 Mix Ratio (Part A: Part B)

— For the injection molding of parts requiring a material with a
medium durometer including: molded rubber stoppers,
gaskets, seals, valves, o-rings and other precision parts

— Suitable for over-molding applications

— Can be used with Ruihe Healthcare color masterbatches for
