Veradel® LTG-3301

About
Veradel® LTG-3301 polyethersulfone (PESU) offers the ability to directly metalize high-quality reflective surfaces for applications that require high heat deflection, excellent toughness and dimensional stability. Other desirable properties include thermal stability, creep resistance, and low moisture absorption. The resin exhibits superior flow when injection molded. Potential applications include automotive headlamp reflectors, fog lamp reflectors, park and turn reflectors, and other applications where excellent surface finish for direct metallization is desired. Veradel® LTG-3301 resin is available in a variety of colors.
