A couple of weeks ago, we shared some information about 3 different types of Elastomeric Materials that were categorized as medical elastomers and discussed the unique properties of our Elast-Eon family of polyurethane-siloxane copolymers.

Today, we would like to delve a little deeper in to the Elast-Eon family of polymers and provide some more information to help you understand its qualities and key uses in developing medical device products.

Elast-Eon was developed in the 1990s by researchers at CSIRO in Australia and first commercialized by AorTech in the early 2000s, Elast-Eon was licensed to Biomerics to produce and market starting in 2013. Biomerics continues to pursue new applications with customers throughout the world because of its properties that combine flexibility, biocompatibility, and biodurability of silicone with the strength and versatility of processing of polyurethane.  Using this technology with our extrusion process, molding, dip-coating, and assembly capabilities we are able to supply Elast-Eon as a resin or to partner more closely with our customers to provide a component, sub-assembly, molded part, coating, or fully assembled device.

The Elast-Eon family of polyurethanes is also part of a larger group of products known as Quadra. Quadra products are medical polyurethanes used in a variety of medical device applications. They are specifically engineered to meet the demanding quality and biocompatibility requirement for the medical device market and are ISO-10993 and USP Class VI complaint. >>Learn More

Here, we highlight just a few current and potential applications where Elast-Eon’s advantages can be crucial to the success of a wide variety of medical devices.

Many design engineers have found Elast-Eon to have just the right combination of properties to enable technologies that would otherwise have diminished performance or even be impossible to achieve. The Elast-Eon product family includes grades with durometers spanning from 77 Shore A well into the Shore D range, as well as various grades that are tailored for extrusion/molding or solution processing, making it an attractive option across a broad spectrum of applications.
