WEB EXCLUSIVE: Injection molding biocompatible silicone valves whose slits won’t close up or “heal” during radiation sterilization is possible with new Silpuran 6610/40 LSR from Wacker Chemical, Adrian, Mich. Valves molded with this 40 Shore A system do not require a release coating to prevent slits from closing, thus saving time and cost. Eliminating the release agent also reduces risk of contamination. The non-healing effect is said to withstand abnormally high radiation doses and allows the silicone valve membrane to be slit prior to post-curing.
