What is low-consistency rubber (LCR)?
Low-consistency rubber (LCR) is a silicone or synthetic rubber compound with lower viscosity and softer consistency compared to traditional high-consistency grades. This makes LCR highly flowable and ideal for mold making, prototyping, potting, supported extrusion, and molding. It offers excellent flexibility, chemical resistance and thermal stability, making it suitable for applications including medical components, in which intricate designs and consistent performance are critical.
