ULTEM 1000 Resin is an unreinforced amorphous polyetherimide (PEI) resin that may offer a high glass transition temperature (Tg) of 217°C. Features are excellent mechanical, electrical and dimensional properties up to high temperatures. The material may offer very good chemical resistance for an amorphous material and is inherently flame retardant offering UL94 V0 and 5V ratings and aerospace FAR 25.853 compliance. The material is RoHS compliant and the natural, uncolored, material is halogen free according to standards IEC 61249-2-21 , IPC 4101E and JEDEC JS709B. For colored variants compliance needs to be checked case by case. The base material is transparent amber colored but is also available in custom colors - transparent and opaque.
