Proto Labs Inc. has added optical-grade liquid silicone rubber to its existing lineup of moldable plastic, metal and LSR materials. The high-performance optical LSR is transparent, Photo Labs said, as well as extremely flexible and starting to replace glass in many optical applications.
The engineering-grade thermoset offers a host of benefits for those developing components and products inside the lighting industry, Photo Labs said. The Optical LSR does not discolor or lose transparency with age or with exposure to heat or UV light; it is significantly lighter than glass and most other plastics; and it is scratch and crack resistant, among many other advantages, Proto Labs claims.
