According to the company, the new materials have high flow, custom colorability and high strength, making it possible to lower injection pressures or mold thinner walls at the same pressure, while avoiding short shots. In contrast to other high-flow glass-reinforced Ultem materials, these new grades maintain the existing color range of existing Ultem 2X10/2X00 resins and can be custom colored for connector identification and product branding, Sabic said.
With glass fiber loadings of 10, 20 and 30%, respectively, Ultem 2120, 2220 and 2320 resins exhibit low viscosity, enabling compact designs with thin walls that expand available space within or surrounding the part. Compared to existing Ultem resins with enhanced flow, these materials demonstrate higher spiral flow properties of up to 36%, according to Sabic.
The resins are also available as International Sustainability and Carbon Certification (ISCC) PLUS certified renewable versions and do not contain per and polyfluorinated substances (PFAS) intentionally added during the manufacturing process.
