Above: SABIC has introduced a new semi- crystalline product in its range of LNP ELCRES CRX copolymer resins
addition to a large portfolio of TPEs developed by Teknor Apex for overmoulding applications in medical devices as well as in the consumer product and automotive industries.” Avient has introduced two new Trilliant health-
care formulations offering improved chemical resistance to hospital-grade disinfectants over other flame-resistant (FR) polymers such as PC/ ABS, PC/PET, and copolyester. Trilliant HC8910 and HC8920 healthcare grades were developed in response to intense disinfecting protocols. Using a method adapted from ASTM D543 for ESCR (environmental stress cracking resistance), the com- pany says that results versus alternative FR materi- als demonstrate superior mechanical and aesthetic property retention, and prevention of cracks and crazing after exposure to leading healthcare disinfectants, such as Virex Tb, CaviCide, Vesphene IIse and Super Sani-Cloth. Trilliant HC8910 and HC8920 series of materials are made without BPA and available in standard or custom colours. The HC8920 grades are formulated to meet certifica- tion to UL94 5VA at 3.0 mm, V-0 at 1.5 mm and V-1 at 0.75 mm.

resins. The company says that these materials offer good chemical resistance to aggressive healthcare disinfectants and can help prevent premature failure from ESC in medical equipment housings and devices. The new grade is the fourth product in the LNP ELCRES CRX portfolio, which comprises amorphous and semi-crystalline materials. The application of increasingly aggressive disinfectants, such as alcohols, peroxides and quaternary ammonium compounds, to combat hospital-acquired infections can lead to ESC and failure in plastic parts. SABIC’s copolymer technol- ogy can resist stress cracking and mitigate crack propagation to help extend the useful life of medical equipment used in hospitals and clinics, as well as homes for remote healthcare devices. Further, LNP ELCRES CRX copolymers can serve as potential drop-in solutions for existing production tooling. The new semi-crystalline LNP ELCRES CRX copolymer features UL V-0 performance at 1.5 mm, good ductility and the portfolio’s highest level of chemical resistance against leading hospital disinfectants. All current LNP ELCRES CRX grades are opaque and custom colourable, and they meet the requirements of limited compatibility according to ISO 10993 (parts 5 and 10). The full portfolio is now included under SABIC’s Healthcare Product Policy, which specifies formulation lock for covered materials and a management of change process.
