SABIC has introduced a PCR-based Noryl  formulated using 25% or more post-PCR 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 SABIC says 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, says SABIC. 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. SABIC says this innovative and sustainable solution is among the first polyphenylene ether (PPE)-based material technologies to incorporate such a significant level of recycled content. 
 
“Our new PCR-based Noryl resin technology is another milestone in SABIC’s long-term strategy to address customers’ sustainability requirements and support circularity,” says Joshua Chiaw, director, Business Management, LNP & Noryl, Specialties, SABIC. “Incorporating a high level of PCR content is just one of our approaches to making our products more sustainable. We have also pioneered chemical upcycling of single-use polyethylene terephthalate bottles and are expanding our use of bio-based feedstocks. These sustainability achievements can be found across SABIC’s Specialties ´óÏó´«Ã½ and demonstrate that we are not simply looking to the future – we are delivering breakthrough products today.”
 
“Developing PPE-based engineering resins with high percentages of recycled material is not trivial and poses a range of technical challenges,” adds Luc Govaerts, technology director, Specialties, SABIC. “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.”
 
Noryl NH5120RC3 resin further supports sustainability with non-brominated/non-chlorinated flame retardance. The material, which may be well suited for electrical applications such as heating/ventilation/air conditioning (HVAC) enclosures and photovoltaic / solar junction boxes, has a UL94 flame rating of V1 at 1.5mm. It also reportedly delivers a good balance of flow, heat performance and creep resistance. 
 
NORYL NH5120RC3 resin is globally available.
