Medical grade Liquid Silicone Rubber (LSR) for Healthcare applications

Elkem Silicones understands how important performance and processability is when producing high quality precision molded parts for the healthcare market. Liquid Silicone Rubbers (LSRs) are typically used with injection molding machines, enabling consistent production of reproducible silicone parts with optimum quality, excellent process control and minimum cost. The material is delivered as a two-part product, where the A part contains the catalyst (platinum) and the B part contains the cross-linker. Both parts are pumped and mixed, metered into the injection unit, the vulcanized under heat and pressure in the mold.

Our expanding Silbione™ LSR product lines offer distinctive advantages for producing high quality precision molded parts for the healthcare market including easy processing, easy release and high-performance physical properties to improve part appearance, functionality, and productivity.
