Discover Silicone Reusable Vacuum Bag for Composite Molding Solutions at JEC World 2025

JEC World in Paris is the only tradeshow that unites the global composite industry. Elkem will be exhibiting at JEC World 2025, the leading composite manufacturing event in the world, joining this show is an opportunity we cannot miss. The participation to JEC World gives us a unique opportunity to meet our customers and the players of this innovative industry.

Composites, a revolutionary material that enables designers and engineers to craft complex and very resistant low-weight parts that can be molded in a great variety of shapes. For many years now, composites have gradually entered into our everyday lives and are today used by a wide range of manufacturers that serve consumers and industrial markets.

We support & develop solutions for the composite Industry for actors along the value chain, from RTV2 used for manufacturing, to high performance silicone elastomers for production of reusable vacuum bags.

The BLUESIL™ RTV 3724 A&B has been developed in partnership with MVP for FlexMolding, a silicone vacuum infusion molding technology designed to accelerate production. This collaborative effort aims to optimize the application experience in membrane construction, extending its lifespan. The two components (A&B) are expertly sprayed using MVP’s equipment that precisely blends and applies the silicone seamlessly. Elkem & MVP are reshaping the landscape of closed molding with a focus on performance, efficiency, and longevity.

The BLUESIL™ RTV 3724 A&B illustrates that an eco-responsible and operator-protective approach is not only beneficial for the environment but also a source of savings and competitiveness. By encouraging industries to rethink their manufacturing processes, it redefines sustainability standards and proves that environmentally friendly innovations are possible and profitable.
