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. CA-45FC produces a 45A shore hardness rubber, and CA-55FC produces a 53A Shore Hardness rubber.

For those new to Elkem Silicone Rubber, we offer Sample Kits.
