SABIC has launched a new portfolio of biobased ULTEM resins that offer sustainability benefits while delivering the same high performance and processability as incumbent ULTEM materials.
These polyetherimide (PEI) materials are the first certified renewable high-performance, amorphous polymers available in the industry. Using a mass balance approach, for every 100 kg of ULTEM resin produced, SABIC replaces 25.5 kg of fossil-based feedstocks with biobased materials derived from waste or residue.
This advanced offering is a drop-in material option for current ULTEM materials and can support customers’ sustainability goals for challenging applications where high temperature, dimensional stability or demanding mechanical performance is required.
The company says biobased ULTEM resins can potentially reduce carbon footprint by up to 10% compared with fossil-based incumbent grades, giving the material the International Sustainability and Carbon Certification Plus (ISCC+) designation.
