Smart Molding International 1-2023

48 smart_molding international 1/2023 materials S ABIC, a global leader in the chemical industry, introduced at MD&M West 2023 two new LNP™ CRX polycarbonate (PC) copo- lymer resins offering a distinct combi- nation of robust chemical and impact resistance, thin-wall transparency, dimensional stability and process- ability. In device applications such as clear covers, screens and display lenses, the new materials can over- come key drawbacks of incumbent PC resins and co-polyester resins when exposed to disinfectants or aggres- sive chemicals. Customers can choose LNP™ ELCRES™ CRX1314TW copo- lymer or its bio-based equivalent, LNP™ ELCRIN™ CRX1314BTW copo- lymer, which offers up to a 42 percent reduction in carbon footprint based on life cycle assessment (LCA). Both grades feature limited biocompatibil- ity according to ISO 10993 and cov- erage under SABIC’s healthcare prod- uct 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 develop- ment of these innovative thin-wall transparent materials. “ T h e r i g o r o u s h e a l t h c a r e disinfection protocols established during the COVID pandemic are ongoing and SABIC continues to innovate in the area of chemical resistance,” said Joshua Chiaw, Director, Business Management, LNP & NORYL, Specialties, SABIC. “Our Specialties business is developing new solutions that not only help device manufacturers avoid degradation from aggressive disinfectants, but also address other requirements. Our newest materials extend the LNP CRX portfolio by combining s i gnature chemi ca l res i stance with other desirable properties, including sustainability. These thin- wall transparent copolymers, which complement our opaque LNP CRX grades, can help customers take a holistic approach when creating diagnostic devices and wearables that deliver longer service life, lower system costs and reduce environmental impact.” Distinct Combination of Properties Like all LNP CRX materials, the new grades feature exceptional resistance to harsh disinfecting chemicals, such as quaternary ammonium compounds, alcohols and peroxides, which can lead to the environmental stress cracking (ESC) of medical device displays and covers. Furthermore, these materials offer transparency Developing innovative thin-wall transparent materials At MD&M West 2023, SABIC launched new chemically resistant, thin-wall transparent LNP™ CRX copolymer resins that can help improve medical device durability & sustainability.
