Two new LNP™ CRX polycarbonate (PC) copolymer resins from SABIC offer a distinct combination of robust chemical and impact resistance, thin-wall transparency, dimensional stability and processability. The materials were introduced at MD&M West in Anaheim. In device applications such as clear covers, screens, and display lenses, the new materials can overcome key drawbacks of incumbent PC resins and co-polyester resins when exposed to disinfectants or aggressive chemicals.
The resins include LNP ELCRES™ CRX1314TW copolymer or its bio-based equivalent, LNP ELCRIN™ CRX1314BTW copolymer, which offers up to a 42 percent reduction in carbon footprint based on life cycle assessment (LCA). Both grades feature limited biocompatibility according to ISO 109931 and coverage under SABIC’s healthcare product policy, which provides stringent management of change processes. Since SABIC’s first LNP ELCRES CRX copolymer resins were introduced at MD&M West 2020, the continued market need for chemically resistant materials has driven the development of these innovative thin-wall transparent materials.
Nithin Raikar, SABIC’s Senior Business Manager for LNP Resins and Compounds, will discuss these new LNP CRX materials tomorrow at MD&M West 2023. His presentation, “Thin-wall Transparent, Chemically Resistant LNP CRX Copolymer Resins: Addressing Medical Device Durability and Sustainability Trends,” will take place on 11:30 AM in the Design Alley Theater.
