Structural insulation is commonly applied in markets with stringent fire safety requirements, such as railways and buildings. Insulation with passive fire protection (PFP) properties is crucial to prevent fires and toxic gases from spreading. PET-based materials have excellent fire-resistant properties, satisfying leading railway (EN 45545-2) and construction standards (EN 13501-1). The closed-cell structure of fire-retardant PET foam shows the lowest heat release and effectively prevents the emission of toxic smoke, such as HCN and irritant gases.

Energy-efficient composite sandwich structures are a powerful way of saving energy and reducing CO₂ emissions. As a leading technology, PET-based foam utilises post-consumer PET beverage bottles to produce high-performing structural foam. By recycling waste material into high-quality insulation resources, PET-based foam cores significantly reduce a project’s environmental impact. This allows specifiers to align with the growing standards for eco-friendly building materials.

The use of shaped thermoplastic composites is a growing trend in multiple industries, such as automotive, public transit and marine applications. Turning flat core materials into a three-dimensional shape includes conversion processes such as sawing, cutting, grooving, or milling. All those converting methods can create off-cuts, sawdust, and additional waste. ArmaPET can help specifiers create simple shapes and geometries. Due to its thermoplastic nature, specifiers can compose complex 3D shapes or double-curved sandwich panels by using thermoforming methods. This results in less waste, more uniform material properties without stress concentration, improved weight and lowered costs.
