One of the key advantages of the newly developed silicone gels from WEVO-CHEMIE GmbH is their viscosity, which is up to 50% lower than standard products available in the market. Additionally, these gels offer a range of adaptable material properties suitable for both large and relatively small volumes, tailored to meet specific component and customer requirements. Examples include the pot life and curing time necessary for efficient production, as well as the penetration hardness for optimal protection against challenging ambient conditions. For instance, the room-temperature-vulcanizing (RTV-2) silicones provide reliable moisture protection for electronic components.

Weinheim, Germany – Global sealing manufacturer Freudenberg Sealing Technologies has developed a new 70 EPDM 335DW compound for O-rings. This

With this new hardener, WACKER is assisting customers in the coatings industry who are increasingly prioritizing sustainability. SILRES® HP 2000 LV can be used to formulate high-solids coatings, for example. Such polysiloxane coatings have a much lower solvent demand and need less-frequent renovation, due to their durability. Furthermore, the fact that SILRES® HP 2000 LV allows for the formulation of two-coat systems conserves resources and improves the sustainability of the coatings.

Researchers from the University of Minho in Portugal started with silicone rubber polymer and added zirconia nanoparticles to make the material attract water molecules. After they rolled the composite material into a thin film, they hardened it with heat and laser-etched a grooved pattern onto the film’s surface that exposed the hydrophilic zirconia nanoparticles. When the film encountered water molecules atop ice, it stuck to the slippery surface because the polymer mimicked the capillary action of slip-resistant gecko footpads.

Dow and Carbice have a groundbreaking partnership to offer advanced thermal interface materials for various industries, including mobility, industrial, consumer electronics, and semiconductors. Unveiled at The Battery Show North America in 2024, this partnershipopens in a new tab combines decades of Dow’s silicone expertise with aligned carbon nanotube (CNT) technology from Carbice. The collaboration supports innovation for diverse applications through thermal management solutions that are reliable, affordable, and customizable.

The FDA has issued a recall for certain VasoView HemoPro Endoscopic Vessel Harvesting (EVH) Systems, adding these devices to the medical device shortage list on November 15, 2024. This recall, classified as Class I, the most serious type, involves removing the affected devices from use or sale. The devices in question are detailed in a Letter to Health Care Providers, which contains the most current information.

The recall affects VasoView HemoPro 1 (VH-3000-W) and 1.5 (VH-3500) models, identified by their unique device identifiers. Getinge, the manufacturer, sent an Urgent Medical Device Removal letter to all affected customers on September 20, 2024. The letter advises customers to examine their inventory, remove the affected devices, and contact Getinge for return authorization and shipping instructions for unused or unexpired products.

Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new method to 3D print sturdy silicone structures that are bigger, taller, thinner and more porous than ever before.

The team’s two-part “fast cure” silicone-based ink for direct ink writing mixes just before printing and sets quickly at room temperature, allowing for longer print times, simplifying the fabrication process, and ensuring structures will not collapse or sag, even in complex shapes and configurations.

H.B. Fuller Company announced that it has signed agreements to acquire two leading medical adhesive technology companies: GEM S.r.l. and Medifill Ltd.
Medifill Ltd. is an Irish formulator and producer of medical-grade cyanoacrylate adhesives with a state-of-the-art clean room and manufacturing capabilities. Medifill produces advanced technology that is specifically tailored for the wound closure market. The next-generation formulations enable fast, safe, and effective wound closure.
GEM S.r.l. is an Italian manufacturer and market leading provider of medical adhesives and innovative application devices approved and certified for over 80 internal indications. The acquisition establishes a European headquarters for H.B. Fuller’s Medical Adhesive Technologies (MAT) business and expands the company’s medical adhesive offerings, further shifting its portfolio toward highly profitable, higher growth markets.

The Neotech Bridge is a silicone nipple cover with a built-in channel that attaches to a syringe filled with breastmilk or formula. The syringe allows mothers to control the amount and flow to keep the baby at the breast, feeding continuously which help to further promote natural milk production.
The market opportunity is vast as a large percentage of mothers experience breastfeeding challenges. While initially targeting hospitals, Neotech is now also focused on the retail space as well. And since taking over the product, Neotech continues to grow sales each year.
Both Neotech and Silcotech emphasized the powerful impact of this product.
