WACKER has vast experience with Liquid Silicone Rubber (LSR) and its associated processing methods. WACKER liquid silicone rubber meets all relevant specifications, is ideal for use in 2K injection molding and has proved to be just as effective for manufacturing precision components as for the mass production of complex parts within narrow tolerances. 


The Future Lies in Hard/Soft Combinations

Liquid silicone rubber and high-performance plastics make the perfect combination for manufacturing sophisticated products used in various industrial applications. These hard/soft combinations are becoming particularly popular in the automotive, electronics, hygiene and medical engineering sectors, where the ever stricter strength requirements cannot be met with conventional technologies.


In anticipation of this growing trend, WACKER developed its ELASTOSIL® LR series of self-adhesive liquid silicone rubbers. WACKER versatile product range for combination with not only engineering plastics, but also metals, glass, etc., offers the answer to all of your challenges. Multicomponent injection molding opens up completely new options for design engineers and product designers.
