AkzoNobel's Expancel receives US FDA nod for in wine corks

 
Sylvia Winkel Pettersson, director of marketing & sales for Expancel, said, “We know that one of the major issues winemakers are encountering is cork taint. This can be reduced or eliminated by cleaning the cork at granule size. By using Expancel microspheres, regular, consistent and clean cork closures can be achieved. In turn, better corks ensure that wines are enjoyed as intended. The winemakers benefit from totally purified corks that make it possible to keep wine in a bottle for decades with consistent quality, which gives them a strong competitive advantage.”
 
Microspheres are small spherical particles that consist of a thermoplastic shell encapsulating a gas. Add heat and the microspheres expand dramatically, up to 60 times their original volume. Expancel is highly compressible and has a capacity to return to shape. AkzoNobel is the leading provider of expandable microsphere solutions worldwide. Offering benefits such as lower density and better insulation, some of the many and varied applications include footwear, paint, printing ink, paper and plastics.

 
“We are only just beginning to explore the potential of Expancel. The opportunities don't stop at cork. For example, its versatility makes it possible to realise innovative ideas for a new generation of packaging and sealing solutions for food products. We definitely have the expertise to take food and beverage packaging even further,” added Winkel Pettersson.
