Proto Labs (NYSE: PRLB) has added the optical-grade liquid silicone rubber (LSR) to injection moulding materials. The optical-grade liquid silicone chosen by Proto Labs has exceptional technical performances, it is transparent, highly flexible and able to replace glass in several applications.

The thermosetting material offers a range of benefits in the production of components and products under development inside the lighting industry. The optical-grade liquid silicone does not discolour and does not lose the transparency with the passing of time or the exposure to heat or ultraviolet rays; besides, it is lighter than glass and most of other thermoplastic materials; among the several advantages, it is very resistant to scratches and to mechanical stresses.HA01_PROTOLABS
