Microagglomerated wine corks

Expancel Microspheres helps to deliver on the potential of microagglomerated cork to overcome some of the weaknesses of traditional cork. Cork is a natural material with excellent properties, but it is also variable. Adding Expancel retains the important benefits and makes performance more consistent. Wine, for example, wants to penetrate cork, which can then harden and lose its properties. Expancel Microspheres reduce this tendency, ensuring more even quality and the optimal granule structure.

Expancel Microspheres are resilient

Expancel is highly compressible and has an outstanding capacity to return to shape. Wine corks made with Expancel Microspheres are easy to insert and mold themselves to form the perfect seal. They enable microagglomerated cork with the ideal granule structure and resilience.

Airtight and shrink free

Expancel expands to form a perfect seal. It does not shrink or absorb moisture, which means the content is protected for long periods. So the wine is in perfect condition when the bottle is opened.

No more cork taint

Cork taint caused by the formation of chemical compounds such as TCA can be eliminated by finely grinding and washing the natural cork. The problem is you lose compressibility. Adding Expancel Microspheres restores it. The result: a taint-free cork with all the right properties. Perfect for the winemaker as well as the wine connoisseur.

Synthetic wine corks

When it comes to synthentic wine corks, it's all in the foaming. As synthetic wine cork generally avoids irregularities associated with natural cork, its use falls short in the foaming process. Expancel Microspheres have a fine, closed and uniform structure that promises highly-controlled foaming for consistent results. This means that you can use Expancel alone or in combination with your chemical blowing agent to achieve a wine cork with outstanding air tight properties improving the shelf time of the wine or beverage. Expancel is not only a blowing agent in wine corks but giving additional value to the product. Cheers to that!
