Sabic has launched a new portfolio of ten LNP™ ELCRIN™ copolymer resins. The polycarbonate (PC)-based copolymer materials contain 50-75 % post-consumer recycled (PCR) content, as certified by SCS Global Services, and can reduce carbon footprint while providing desired performance properties and aesthetics. LNP compounds are made by melt blending plastics with reinforcing materials and additives to improve properties.
Compared to impact-modified PC resins with PCR content, which can have performance limitations, the new LNP copolymer resins offer consistently high performance, the company says. Depending on the grade, they offer low-temperature ductility, chemical and weathering resistance, good flow properties for ease of processing, transparency, UV stability, and thin-wall flame retardancy (FR) that meets UL94 V-0 rating at 0.6 mm. They also offer a wider range of colors for opaque materials and multiple transparent options.
According to the company, the new LNP copolymer resin grades outperform competitors’ modified PC grades made with recycled content. While these competitors contain similar proportions of PCR material, they can only offer one or two of the improved properties of the SABIC grades, according to the company.
SABIC’s improved LNP copolymer resins have a wide range of potential applications, including consumer electronics and charger housings, 5G base station infrastructure, and various industrial components such as closed-loop systems and heat pumps. Moreover, in the automotive industry, these resins maybe used in exterior grilles, pillars, and trim components.
