Improved Chemical Resistance Materials for Medical Enclosures and Housings
With patient safety at the forefront, the healthcare industry is mobilizing to address the concerns of increasing patient infections associated with medical care, known as hospital-acquired infections (HAIs). To help meet this challenge, medical equipment and high touch surfaces in patient care settings are repeatedly wiped down with increasingly aggressive chemical disinfectants.Chemical Resistance Data - Environmental Stress Cracking (ESC) Performance
Compared to traditional PC, ABS, PBT and co-polyester resins and blends which are potentially incompatible with highly aggressive disinfectants such as quaternary ammonium compounds the new LNP ELCRES CRX resins can help prevent stress cracking and mitigate crack propagation.
SABIC’s LNP ELCRES CRX resins leverage unique copolymer technology to provide improved chemical resistance for healthcare devices and equipment, compared to existing materials used such as PC/ABS, PC/PBT, or co-polyester resins and blends.
