SABIC unveiled its LNP™ ELCRIN™ iQ portfolio of polybutylene terephthalate (PBT) compounded resins derived from recycled polyethylene terephthalate (rPET) to support the circular economy and help reduce plastic waste.
By chemically upcycling consumer-discarded PET (primarily single use water bottles) into higher-value PBT materials with enhanced properties and suitability for more-durable applications, the company is encouraging the use of recycled resins. These products also offer a smaller cradle-to-gate environmental footprint than virgin PBT resin, as measured by Cumulative Energy Demand (CED) and Global Warming Potential (GWP).
SABIC’s LNP™ ELCRIN™ iQ compounds and blends are based on upcycled iQ PBT resins, a proprietary SABIC technology. This technology overcomes some of the limitations of mechanical recycling by using chemical processes to depolymerise PET bottles and other PET waste into their precursor chemicals, purify them and then use them to create new PBT resin. The technology can deliver performance and processing benefits such as good chemical resistance, colourability, high flow for faster throughput and flame retardance (FR).
