About the Product Family
PLEXIMID® from RÖHM combines the advantages of PMMA (polymethyl methacrylate) with a higher heat deflection temperature. Like the PMMA PLEXIGLAS®, this engineering plastic offers great optical quality and light transmission as well as resistance to UV, wear and weathering.
Due to its increased heat deflection, PLEXIMID® from RÖHM is predestined for demanding applications, like headlamps that either have a very high performance and brightness or where the LED is installed closely to the lens. The PMMI has been tested under prolonged thermal load, being exposed to 150 °C for 40 days, with minimal effects on transparency or optical quality. No yellowing or clouding occurred.
