Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams
COMPOCEL® ALF is a lightweight panel composed by a core in EPS "extruded polystyrene" and bonded with aluminium faces. Foam core is offered in different densities while aluminium faces (skins) can be painted according to the needs of our clients. Normally, COMPOCEL® ALF is applied in vans and in the building sector.
