Introducing Liquid Silicone Rubber (LSR) from Trelleborg

Two years ago, Trelleborg Sealing Solutions purchased a liquid silicone company headquartered in Switzerland, which provided silicone extrusion and silicone molding, all in a clean room facility. The facility in Stein am Rhein, Switzerland and another in Northborough, Mass., allows the company to manufacture and design two-part Liquid Silicone Rubber (LSR) devices and components for the medical, biotech, pharmaceutical, and food and beverage industries.

Liquid silicone rubber is best suited to life science applications because it features matchless inertness and bio compatibility, which should be considered when factoring in potential bacteria growth and alleviating contamination. Silicone rubber is compatible with human beings and its mechanical properties are highly suitable for dynamic applications where accuracy, consistency and longevity are required.
