3A Composites (Sins, Switzerland) highlights its recyclable, fire-safe Airex system core product line for structural composite panels.  

Airex rigid foam core materials are compliant with ASTM E-84 fire, smoke and toxicity (FST) standards. 3A Composites also says that because core is only one component in a sandwich panel, it works with its supplier partners to help ensure FST standards are met.

Airex system core is also said to be ideal for holding screws and inserts, with a product line ranging from simple high-density core to lower-density core suited for strategically placing customized inserts. 

Additional benefits include light weight, sustainable and recyclable core options and low net cost. According to 3A Composites, low-priced core can often result in higher overall costs in the final laminate. In the case of the Airex product line, the company offers low resin absorption cores with recommended laminates and testing to make sure the correct properties and amount of core are used, reducing overall costs.

The company’s specialty is determining the correct balance and mix between high density cores and the high R values of lower density cores. 3A Composites works with customers to ensure the target properties are achieved. Its state-of-the-art R&D lab is available to test final laminates to make sure the core is meeting physical property requirements.

In addition to Airex foam, 3A Composites also offers a selection of other products such as Soric nonwovens and Baltek balsa core.
