ULTEM™ Resin DT1820EV

Chemical Family: Polyetherimide (PEI)Polyimides (PI)

SABIC's Specialties Business ULTEM™ Resin DT1820EV is a highly versatile polyetherimide (PEI) blend designed for injection molding applications in the mobile phone, computer, and tablet industries. With excellent mold release properties and enhanced ductility, this high-flow resin is ideal for producing parts with complex geometries and high gloss finishes. Its internal mold release helps streamline the manufacturing process, while its enhanced ductility ensures that parts are more resistant to cracking and breaking.

Note

ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.; ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.; ¹¹ The information stated on Technical Datasheets should be used as indicative only for material selection purposes and not be utilized as specification or used for part or tool design.

Benefits

Long Term Heat Resistance: Excellent stability of physical and mechanical properties at elevated temperatures thanks to high glass transition temperature of up to 280°C. Available with relative thermal indices (RTI) higher than 200°C (preliminary).
Strength and Stiffness: Outstanding strength, stiffness and creep resistance with predictable performance up to 230°C (preliminary). EXTEM™ XH resin is approximately 50% stronger at 170°C than ULTEM™ resin. Unfilled, transparent grades are equal in strength to other thermoplastics with opacifying fillers.
Dimensional Stability: Among the most dimensionally stable thermoplastics available, offering predictability over a broader temperature range exceeding 200°C. Filled grades offer exceptionally high-tolerance dimensional capabilities.
Environmental Stress & Cracking Resistance: Unlike most other amorphous thermoplastics, EXTEM™ resins retain strength and resist stress cracking when exposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols, acids as well as chlorinated solvents such as methylene chloride.
Flammability, Smoke Generation and Toxicity: Inherently flame-retardant without the use of halogenated additives, which can pose an environmental risk. EXTEM™ resin is exceptionally difficult to ignite, with a limiting oxygen index (LOI) of 45% (preliminary). EXTEM™ resin is expected to retain the UL performance and flame, smoke and toxicity strengths of ULTEM™ resin.
Processability: EXTEM™ resin can be processed in conventional drying and injection molding or extrusion equipment capable of running ULTEM™ resin and other high heat thermoplastics. EXTEM™ resin can be film and profile extruded, thermoformed, extrusion blow molded, extruded into stock shapes, and injection molded. Flowability can be tailored to meet customer applications through product and processing design and flows similar to ULTEM™ resins.
