New Self-Adhesive Liquid Silicone Rubber from WACKER

Nordmann partner WACKER has developed ELASTOSIL® LR 5471, a new self-adhesive liquid silicone rubber that does not require time-consuming thermal post-curing and offers excellent mechanical properties. The material is particularly well-suited for the efficient production of hard-soft composite components and adheres reliably to various metals as well as thermoplastics such as PBT and PET; it was specifically developed for the large-scale production of overmolded parts and co-molding procedures. 

Nordmann is pleased to market this innovative product in Europe. A distinctive feature of ELASTOSIL® LR 5471 is its very low content of volatile components after curing. As a result, even without post-curing, the material meets the requirements for food-contact applications in accordance with the recommendations of the German Federal Institute for Risk Assessment (BfR) as well as the corresponding national requirements in other European countries.

Potential applications range from cooking and kitchen utensils to medical products and infant care components. In addition, the new liquid silicone rubber offers impressive elasticity and strength. With an elongation at break of up to 570 percent and a tensile strength of up to 38 N/mm, the material is also suitable for demanding applications such as seals, flexible scrapers for baking and kitchen utensils, or medical components.

This new development once again underscores WACKER’s innovative strength, which Nordmann, as a long-standing partner, particularly values. Since the start of their strategic partnership in the field of silicone elastomers in 2025, both companies have been continuously expanding their joint market presence in Europe and driving forward innovative silicone solutions for a wide variety of applications. The full WACKER press release regarding the new ELASTOSIL® LR 5471 product, dated September 7, 2026, can be found here.
