WEB EXCLUSIVE: A new high-performance, fully transparent nylon 11 from Arkema Inc., Philadelphia, is designed for breathing masks, tubing, and other medical-device components worn for continuous periods. Demand for such products is increasing to meet the rise in home healthcare.
Rilsan Clear G-170 MED is said to be more transparent than glass and lighter and more flexible than polycarbonate for applications in which patient comfort is required. High clarity of components used in these devices can improve function and aesthetics. This material is sterilization resistant; its light transmittance is 91%—better than glass—and its specific gravity is 1.05, 12% lighter than other clear medical plastics such as PC, resulting in devices that are easier to carry or wear for extended periods of time. Such complex devices often require flexibility for both easier assembly and improved patient comfort and mobility. Rilsan Clear has a flexural modulus of 293,000 psi, 16% greater flexibility than PC.
