9/30/2013 12:00:00 AM - Advanced Technologies | Electronics | Silicone's high adaptability lends itself to optimization for varying levels of conductivity, permeability, and other properties desirable for use in electronic systems.

A Brief History and Evolution of Key Regulatory Requirements for Silicones

8/1/2013 12:00:00 AM - Biomaterials | Medical Implants, General Healthcare | Due to silicone’s ever-expanding role in medical devices; industry practices, standards, and regulations have and will continue to evolve.

New Innovations in Silicone Technology for Aircraft and Aerospace

7/24/2013 12:00:00 AM - Advanced Technologies | Space, Commercial Aviation | New innovations in silicone technology that add to silicone’s prolific resume and success in the aerospace and aircraft industries are fuel and solvent resistant silicone elastomers, silicone ice-release coatings for aerodynamic surfaces, and controlled volatility silicone film adhesives.

Medical-Quality Silicones and Skin Care

7/9/2013 12:00:00 AM - Biomaterials | Skin Care | As the body’s largest organ, not to mention its protective shield against the outside world, skin should be treated with the same care as any other body part. This level of care can be provided by silicone; innovation in silicone technology from its history in healthcare and especially medical implant applications need only be extrapolated and applied. The crossover between silicones for medical implants and for skin care lies in material purity.

Silicones in Ophthalmic Applications

6/28/2013 12:00:00 AM - Biomaterials | Medical Implants | Assuming a natural rather than intrusive feel is a task of medical devices, and silicone rises to the challenge to help achieve this. In ophthalmic applications, silicone allows the benefits and not the burden of a device to meet the eye.

Silicone Ice-Release Coatings

5/21/2013 12:00:00 AM - Advanced Technologies | Defense, Commercial Aviation | When ice builds up on the leading edges of aerodynamic surfaces, it decreases lift and increases drag. Ice-release coatings significantly reduce the force required to remove ice that has adhered, for safer, more efficient use of aircraft vehicles.

Designing Silicones for Medical Device Applications: An Overview

5/16/2013 12:00:00 AM - Biomaterials | Medical Implants, General Healthcare | A recent study by NuSil Technology evaluated the effects of barium sulfate (BaSO4) on the durometer and tensile strength of an implant-grade silicone elastomer, NuSil’s MED-4765.

Thermally Conductive Silicones for Space and Aircraft Applications

5/6/2013 12:00:00 AM - Advanced Technologies | Space, Defense, Commercial Aviation | Silicones are highly resilient materials commonly used as adhesives and encapsulants in aircraft and aerospace applications. A valuable benefit of silicones is their ability to incorporate a variety of filler types that can impart such properties as thermal conductivity at elevated temperatures. Thermally conductive silicone adhesives and encapsulants aid in the removal of heat without adding additional stress to electronic assemblies and other devices during thermal cycling.

Versatility of Silicone for Electronics in Medical Devices

10/9/2012 12:00:00 AM - Biomaterials | Medical Implants, General Healthcare | Since the first use of silicone for medical applications in the 1950s, this material’s chemical stability, physical strengths, and bioinertness have proven it a valuable candidate for medical device applications. Best of all, silicones are so dynamic they can be formulated to achieve specific performance, aesthetic, or therapeutic properties that aren’t inherently available with silicone elastomer chemistry alone.

Troubleshooting: Platinum Catalyzed Silicones

10/1/2012 12:00:00 AM - Advanced Technologies, Biomaterials | Whether an inhibitor stalls or permanently stops a silicone from curing depends on the catalyst utilized. Understanding the effects of different inhibitors on the catalyst utilized is key to working with curable silicone systems so as to fully benefit from their unique and useful properties. A platinum catalyst allows silicones to be formulated to provide a wide range of physical properties, adjustable work times and reaction rates if cured in the right conditions.
