Iranpolymer\/Baspar <\/em><\/strong>Munich, Germany \u2013 At this year\u2019s COMPAMED medical technology tradeshow, WACKER will be presenting customized silicone rubber grades that set new standards with their optimized properties in terms of haptics, tensile strength and adhesion. Products in the limelight are addition-curing solid silicones for the manufacture of medical and pharmaceutical tubing, for example for use in peristaltic pumps, heart-lung machines and infusion sets. SILPURAN\u00ae silicone adhesive gels are another highlight. They are suitable for coating wound dressings and fixation aids in order to attach portable sensors, dosing devices and wearables to the skin. In parallel with MEDICA, this year\u2019s COMPAMED takes place in D\u00fcsseldorf, Germany, from November 11 to 14.<\/p>\n

Resistant to bodily fluids, radiation and ozone, pleasant to the touch, insensitive to heat, mechanically robust and biocompatible: this property profile makes silicone elastomers a preferred material in medical technology. What\u2019s more, WACKER is almost unrivaled in its ability to tailor silicones to specific applications and production pro-cesses. With its silicone specialties, the chemical group has been a leading solution provider for the medical technology and pharmaceutical industries for years.<\/p>\n

At this year\u2019s COMPAMED, WACKER will be showcasing three solid silicone grades that have already proven themselves many times over: ELASTOSIL\u00ae R plus 4305, ELASTOSIL\u00ae R plus 4360 and ELASTOSIL\u00ae R plus 4366. These addition-curing solid silicone rubbers are ideal for medical technology applications, as no peroxide byproducts are formed during curing. Tubes extruded from such silicones can be used in heart-lung machines, dialyzers, ventilators, infusion systems and catheters, for example. Silicone rubber tubing is also increasingly in demand for the production of drugs and vaccines, as this kind of tube is extremely compatible with mRNA and mRNA-based vaccines.<\/p>\n

ELASTOSIL\u00ae R plus 4305 has excellent mechanical properties. Tubes or components made of this material are particularly durable and are characterized by high bursting strength. They are also compatible with mRNA technology. ELASTOSIL\u00ae R plus 4360 has particularly high rebound resilience and a low compression set. It is particularly suitable for the manufacture of durable tubing for peristaltic pumps.<\/p>\n

Cured rubber products made from ELASTOSIL\u00ae R plus 4366 have particularly low-friction surfaces. Its coefficient of friction is 50 to 70 percent lower than that of comparable standard solid silicones. Tubes made from ELASTOSIL\u00ae R plus 4366 have an oil-free but extremely low-friction surface and are therefore easy to assemble, often even automatically. Thanks to its lower sliding friction, this product, too, is perfect for the manufacture of peristaltic tubes.<\/p>\n

An innovative liquid silicone rubber for hard\/soft combinations will be another center of attention at the show. ELASTOSIL\u00ae LR 3078 makes it possible to manufacture components consisting of a thermoplastic \u2013 such as polycarbonate, polysulfone, polyethersulfone or polyphenylsulfone \u2013 and a soft, elastic silicone component, as is often the case, for example, with ventilation and anesthesia masks. This type of mask has a soft cushion that adapts perfectly to the contours of the face, ensuring a tight fit. Soft and hard components must adhere firmly to each other and must not come loose.<\/p>\n

ELASTOSIL\u00ae LR 3078 was especially developed for 2K injection-molding. It creates strong adherence to the thermoplastic during curing. Surface pretreatment is not necessary. Short cycle times are possible thanks to rapid curing. What\u2019s more, ELASTOSIL\u00ae LR 3078 is characterized by low mold fouling. This supports the uninterrupted operation of the injection-molding machine.<\/p>\n

Cured rubber products made from ELASTOSIL\u00ae LR 3078 achieve very good mechanical properties even without postcuring. In this way, components made of polycarbonate and other heat-sensitive plastics that do not tolerate excessively high processing temperatures can be manufactured, too. Cured rubber made of ELASTOSIL\u00ae LR 3078 is biocompatible and can be steam-sterilized at a temperature of 134 \u00b0C without impairing the mechanical properties of the elastomer or its good adhesion to the plastic. ELASTOSIL\u00ae LR 3078 is suitable for the manufacture of face and ventilation masks, but also for drug delivery systems and devices for minimally invasive procedures.<\/p>\n

SILPURAN\u00ae 2114 and SILPURAN\u00ae 2124 silicone gels will also be on display at WACKER\u2019s COMPAMED booth. Both products achieve a high adhesive strength and are therefore suitable as adhesives for wound dressings and fixation aids.
\nDesigned for Wound Dressings and Wearables
\nSilicone adhesives are the third product group that WACKER will be showcasing at COMPAMED. This time, the focus is on SILPURAN\u00ae 2114 and SILPURAN\u00ae 2124. Both grades achieve a significantly higher adhesion than standard silicone adhesive gels. SILPURAN\u00ae 2114 achieves an adhesive strength of 3.5 Newtons per 2.5 cm2, while SILPURAN\u00ae 2124 achieves an impressive 6.0 Newtons. Both silicone adhesives are suitable for atraumatic wound dressings and can also be used for attaching sensors, dosing devices, colostomy bags and wearables to the skin. Despite their good adhesion, these fixation aids can be removed gently and painlessly.<\/p>\n

Both SILPURAN\u00ae grades are 2K systems. They crosslink to form water-repellent cured rubber. This is breathable, thus making it possible to produce extremely skin-compatible fixation solutions. No residue remains on the skin, when the dressing or tape is removed. The gels also offer excellent adhesion values after repositioning. SILPURAN\u00ae 2114 and SILPURAN\u00ae 2124 can be combined with certain polyolefin release films. Such films can be removed without leaving any residue before being applied to the skin. The release force of the adhesives remains unchanged even after several months of storage.<\/p>\n

At this year\u2019s COMPAMED, WACKER is offering yet another highlight in the form of a sneak preview. A video will be shown that provides insights into a current research project at WACKER\u2019s US site in Ann Arbor (Michigan). Silicone experts there are already work-ing on the next generation of silicone gels. These products adhere ten times more strongly than previous products. Going forward, such silicone adhesives can also be used to reliably attach heavy mobile measuring devices such as glucose sensors or electrocardiographs to the skin.<\/p>\n
