High-performance optical liquid silicone rubber (LSR) from Proto Labs is a transparent, flexible material that can replace glass in many optical applications. The injection-molded thermoset does not discolor or lose transparency with age or with exposure to heat or UV light. It is significantly lighter than glass and most plastics, and is scratch and crack resistant. A key advantage of the material is its ability to reduce the bill of materials in a final assembly. With optical LSR, two parts, such as a lens and seal for lighting applications, can be combined into a single part, which reduces cost and inventory.
