A resin is referred to as bio-based if part or all of its constituent monomers come from biological sources. These sources are derived from plants, such as maize or soybean waste products from the production of biodiesel fuel. Potatoes, lignocellulose, whey, sugar beets, sugar cane, and algae are further alternatives.
Bio-based polymers made from renewable resources are the best choice for cutting back on the use of plastic pollution-causing food packaging materials made from fossil fuels.
The Global Bio-Based PEI resin market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Sabic launches the world’s first bio-based, certified renewable PEI.The Ultem brand name will be used to sell a new portfolio of bio-based polyetherimide (PEI) resins from Sabic that offer the same excellent performance and processability as its conventional equivalents.
The new materials, according to the business, are the first amorphous, high-performance renewable polymers on the market. Using a mass balance method, Sabic replaces 25.5 kg of fossil-based feedstocks with bio-based resources made from waste or leftover, such as crude tall oil from the timber sector, for every 100 kg of Ultem resin produced.
These resins are appropriate for applications in consumer electronics, aerospace, automotive, and other industries where high temperature, dimensional stability, or demanding mechanical performance are required as a drop-in material option to replace current Ultem materials.
Consumer electronics (wearables and mobile devices), automotive (under the hood (UTH) applications such as connectors, sensors, and valves), aerospace (interiors including panels and trim), healthcare (surgical devices and sterilisation trays), and electrical/electronics (5G networking infrastructure) are some potential markets and examples of applications for these resins.
According to an internal assessment that adhered to the general guidelines of life cycle analysis in accordance with ISO 14040/14044 standards, Sabic’s bio-based Ultem resins have the potential to lessen the carbon footprint of the materials by up to 10% compared to incumbent grades made of fossil fuels.
In the cradle-to-gate comparison of these resins, Sabic used its own primary data along with the most recent manufacturing data and industry average estimates.
The Restriction of Hazardous Substances (RoHS) directive and the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation are also complied with by the bio-based Ultem resins.
The performance characteristics of the new Ultem materials, which include long-term high-temperature performance, chemical resistance, excellent mechanical and structural properties, dimensional and hydrolytic stability, excellent processability, and inherent flame retardance, are unaffected by the bio-based feedstocks used in making them.
