Munich - Wacker will be unveiling a new liquid silicone rubber for radiation-sterilizable silicone valves used in medical devices at this year’s international trade fair for high-tech solutions for medical technology, Compamed. The product, available under the name Silpuran 6610/40, serves in the production of biocompatible silicone valves whose slits do not close up or “heal” during radiation sterilization. The new silicone rubber allows such valves to be made without the use of additional auxiliaries. For instance, silicone valves ensure that infusion systems administer the correct dose of liquid medication. Medical equipment for administering liquid medication frequently employs valves made from silicone elastomers. These offer high dosing accuracy, are biocompatible and can be very readily sterilized on account of their resistance to heat, radiation and chemicals. However, it is not unknown for the slits of such silicone valves to close up (“heal”) when radiation-sterilized, a common practice in medical technology.
