Design Considerations For Liquid Silicone Rubber

Source: Protolabs, Inc.

Liquid Silicone Rubber (LSR) is a thermoset material that differs from thermoplastic injection molding in that it is designed to withstand constant temperatures up to 600°F. In addition to high heat resistance, LSR can also endure temperatures falling into the double digits below 0°F while maintaining its flexibility. LSR material has excellent thermal, electrical, and chemical properties, making it ideal for use in a wide range of applications. This article discusses the considerations designers should keep in mind when working with LSR, and offers helpful tips and comparisons for different tasks that LSR would be used for.
