SABIC introduces a PC copolymer resin with excellent chemical resistance 2024-12-18 SABIC has introduced a new LNP™ ELCRES™ CXL polycarbonate (PC) copolymer resin that boasts outstanding chemical resistance. These special materials are designed specifically for customers in the mobility, electronics, industrial, and infrastructure markets. They address the issue of exposure to harsh chemicals that can cause environmental stress cracking and premature failure. In addition to offering greater chemical resistance than existing materials, the LNP™ ELCRES™ CXL copolymer resin can also enhance the durability and reliability of parts, while providing excellent low-temperature impact resistance and weather resistance. Outperforming PC/ABS blends, the new LNP™ ELCRES™ CXL copolymer resin offers excellent chemical resistance, with performance that exceeds that of traditional amorphous materials such as polycarbonate (PC) resins and acrylonitrile-butadiene-styrene (ABS) blends. Internal tests conducted by SABIC have shown that the LNP™ ELCRES™ CXL copolymer resin exhibits high resistance to a variety of chemicals commonly found in the transportation, industrial, infrastructure, and electronics sectors. Representative transportation and infrastructure chemicals were tested, including gasoline, antifreeze, caustic soda (5% solution), and various related chemicals. For industrial applications, typical chemically exposed substances were tested, including asphalt cleaners, brake fluid, and many other substances. In situations where consumers come into contact with transportation, industrial, and infrastructure equipment, the LNP™ ELCRES™ CXL copolymer resin provides greater chemical resistance for ingredients used in hand creams, sunscreens, insect repellents, cleaning solutions, and hand sanitizers. Maureen MacDonald-Stein, Director of Portfolio Strategy and Marketing at SABIC’s Polymers Specialty Business Unit, said, “Multiple trends are exposing plastic components to greater chemical risks.” After the pandemic, concerns about cleanliness remain, prompting consumers to frequently disinfect surfaces ranging from smartphone screens to the handles of electric vehicle chargers. The increasing popularity of wearable devices and the continuous use of smartphones mean that electronic products are constantly in contact with skin oils, lotions, and other personal care products. Our new LNP™ ELCRES™ CXL material helps maintain the performance and aesthetics of components, even as chemicals become more aggressive and exposure increases. ”
With low-temperature toughness down to -60°C, SABIC’s new CXL product portfolio offers a wide range of options, including opaque and non-flame-retardant (FR) transparent grades, opaque thin-wall FR grades, and glass-reinforced versions. These materials also possess value-added properties, such as bromine-free/chlorine-free FR in thin gauges. They offer low-temperature toughness down to -60°C, high fluidity for easy processing, and good colorability to meet aesthetic requirements. They meet the ultraviolet (UV) and water immersion requirements (f1 rating) necessary for outdoor applicability, complying with the UL 746°C standard. To help achieve carbon neutrality, SABIC offers a new bio-renewable version of its LNP™ ELCRIN™ CXL brand materials, which is ISCC PLUS certified. They use bio-based alternative materials with a lower carbon footprint compared to traditional raw materials. Compared to their traditional counterparts, these bio-based grades can reduce carbon dioxide (CO2) emissions while maintaining the same performance. These grades are new products added to the SABIC TRUCIRCLE™ program, which aims to help companies around the world achieve their sustainability goals. Scott Fisher, Technical General Manager of SABIC’s Polymer Specialties Business Unit, said, “Our LNP™ ELCRES™ CXL copolymer resin can help manufacturers and brands address the growing risk of performance and aesthetic degradation resulting from the wider use of chemicals.” ‘Our proprietary copolymerization technology can address the challenge of protecting applications from damage and value loss caused by these substances. By helping to extend the service life of components, LNP™ ELCRES™ CXL materials contribute to sustainability, brand reputation, and customer satisfaction. ”
