Silicone mold-making to meet the most demanding needs

Molding is used for the reproduction of fine details in artwork and architecture to the making of large prototypes for such industries as transport, renewable energy and foundry work, and from food to fashion and cosmetics. Mold-makers and die-casters require very specific materials with the right mechanical properties that facilitate their processes and guarantee quality products reliably, efficiently and cost-effectively. Increasingly, they must meet very demanding regulatory standards, at all stages from manufacturing to end-user safety and they must develop more sustainable, environmentally friendly and non-toxic products, while reducing waste during the mold-making process.

For nearly 60 years now, Elkem Silicones has been developing its BLUESIL™  RTV-2 range for a very wide array of applications in a multitude of industries that require accurate and innovative mold-making techniques. It has established itself as a global leader in the silicones mold-making market, through its vast offering of products and constant improvement through R&D, but above all, by working closely with its customers to respond to their changing needs. 

What are the main advantages of silicone-based formulations for mold-making?
