V-340 Mold Making Silicone Rubber (Low Viscosity)


Popular Specifications
25-33A Shore Hardness  •  170-180 ppi Tear Strength
25,000 cps Viscosity
Elkem V-340, formerly Bluestar Bluesil V-340, is one of our most popular silicone rubber systems for prototype molding applications due to its low viscosity, high strength, and economical price point. This versatile system also offers the flexibility of different cured hardnesses depending on the catalyst used.

The Fast Cure catalysts produce a harder silicone and reduce demold time from 16 hours to only 4 hours, making them excellent options when same-day demold is required.
