SABIC recently announced its new PCR-based NORYL resin technology, formulated using 25% or more post-consumer recycled (PCR) content and aimed at providing additional, sustainable material options for customers. The technology was validated through the commercialization of several grades, including NORYL NH5120RC3 resin containing 30% PCR content, which helps to lower its global warming potential (GWP) by 10 percent compared to the incumbent, fossil-based grade.

The latest PCR-based technology can be incorporated into more than 200 existing NORYL resin grades, as well as an unlimited number of new grades based on specific customer requirements. These include a glass fiber-reinforced grade and an unreinforced, non-FR grade.

Further, SABIC offers resin customization services to meet specific application requirements, as well as a full array of technical support services. It can help support circularity while maintaining the robust physical properties required for demanding applications. This innovative and sustainable solution is among the first polyphenylene ether (PPE)-based material technologies to incorporate such a significant level of recycled content.

SABIC’s NORYL resins have found various automotive applications due to their excellent properties such as high heat resistance, mechanical strength, electrical insulation, and chemical resistance. Examples of automotive applications where NORYL resins have been utilized include:

• Electrical Components such as connectors, sockets, switches, and relay housings. The resins’ high dielectric strength and electrical insulation properties make them suitable for these applications.

• Under-the-Hood Components including engine covers, intake manifolds, and thermostat housings. The high heat resistance and dimensional stability of NORYL resins make them capable of withstanding the elevated temperatures in the engine compartment.

• Battery Components such as battery cell holders, connectors, and cooling system parts. The resins’ flame-retardant (FR) properties and chemical resistance make them a viable choice for battery applications.

• Lighting Components such as headlamp reflectors, lens housings, and LED modules.

• Safety System Components such as airbag housings and seatbelt retractor covers.

Developing PPE-based engineering resins with high percentages of recycled material is not trivial and poses a range of technical challenges. With our product and process expertise, our scientists developed a new PCR-based portfolio, and we are now launching our first flame-retardant NORYL material with consistent performance, including hydrolytic and dimensional stability and mechanical property retention in harsh outdoor environments. Depending on application requirements, customers may be able to replace incumbent, fossil-based NORYL grades with our new PCR-based technology and achieve desired performance while reducing their carbon footprint.
