3A Composites

3A Composites Core Materials is a global organizational unit within 3A Composites, part of Schweiter Technologies (SIX Swiss Exchange: SWTQ), with operations in Europe, the Americas, India, China and Papua New Guinea, that has pioneered the sandwich technology for almost 70 years. Its AirexBaltekBanova brand provides sustainable, lightweight and resource-friendly, high-quality core materials (broadest portfolio in the industry) to enable the production of lighter and thus more energy efficient end products for multiple applications such as wind turbine blades, nacelle covers, hull of a boat, automotive parts, bridge component, etc. All of these are products containing solutions by AirexBaltekBanova for the development, production, and distribution of lightweight composites and lightweight solutions for construction applications. For more information visit:

Alcan Composites (Sins, Switzerland; Northvale, N.J., USA) announced on April 29th, 2010 that changed its group name to 3A Composites. This change followed the 2009 acquisition of Alcan by Schweiter Technologies. For further information visit:
