Consumer Electronics companies often use combinations of glass and metal in their flagship products to provide a high-end, differentiated design to the consumer. However, designing with metal can result in potentially high costs and long production cycles. ULTEM DT1820EV resin may provide an alternative to metal – a lower cost solution that offers comparable performance and similar appearance.


High performance ULTEM DT1820EV resin supports thin-wall, high gloss designs and is an excellent candidate for metal replacement thanks to its surface hardness, good mechanical performance and resistance to UV and chemicals.


Because of its high modulus and surface hardness, ULTEM™ DT1820EV resin is well-suited for metallization using sputtering PVD. The excellent appearance and good mechanical properties can help to replace metals and may reduce production costs.

PVD is a simpler process compared to Non-conductive Vacuum Metallization (NCVM) used with glass fiber filled polycarbonate (PC). PVD provides a better metallic appearance than NCVM and since color is determined by the PVD layer, this method can eliminate the 3 coating steps used in NCVM. In addition, ULTEM DT1820EV resin’s high heat resistance enables the use of higher temperatures in the PVD process which can improve adhesion and cycle time.


A new portfolio of bio-based ULTEM resins that delivers a lower carbon footprint while offering the same high performance and processability as incumbent ULTEM materials is now available.
