Global chemicals company Sabic reported today that it has introduced the first grade in its family of polycarbonate (PC) copolymer resins to be formulated without fluorine or other per- and polyfluoroalkyl substances (PFAS), the so-called “forever chemicals.”
The LNP Elcres NPCRX9612U resin is certified under UL 746G, an outline of investigation for non-fluorine and non-PFAS containing materials. It defines a methodology for evaluating PFAS in virgin and recycled resins with clear sample and test requirements based on material type, said UL on its website.
The problem with PFAS
Because they resist degradation over long periods of time, PFAS have been dubbed “forever chemicals.” They have been used historically in numerous products, including cookware and packaging, because of their non-stick, stain-resistant, and fire-retardance properties. Some studies have shown potential links to human health conditions. Because of that as well as environmental concerns, many countries have implemented restrictions on the use of PFAS, causing demand for PFAS-free materials to soar.
Sabic is responding to that demand by investing in the “research and development of new materials that can help OEMs get ahead of the curve in compliance and performance,” said Sergi Monros, vice president, Sabic Polymers, Specialties BU. The LNP Elcres NPCRX9612U resin grade is the latest example.
Resin withstands harsh healthcare disinfectants
The material’s chemical resistance enables it to withstand harsh healthcare disinfectants while providing UL 94 V0 flame retardance at 1.5 mm for thin-wall geometries. The impact-resistant resins can help manufacturers across multiple industries anticipate and adapt to increasingly stringent regulatory requirements and performance demands, added Sabic.
The biocompatible, custom-colorable grade enables thin-wall, miniaturized device designs, such as insulin pumps, diagnostic imaging devices and monitors, according to Sabic.
Growing portfolio of medical-grade materials
The new resin joins Sabic’s portfolio of medical-grade thermoplastics, which includes LNP Lubriloy compounds and Ultem HU resins. LNP Lubriloy compounds use a proprietary, non-polytetrafluoroethylene (PTFE) internal lubrication technology to achieve wear resistance and low friction without the use of PFAS. Ultem HU resins are unreinforced polyetherimide (PEI) materials featuring mechanical, electrical, and dimensional properties along with chemical and heat resistance.
