Three product lines, 
one promise: green.


Armacell is the pioneer in the field of polyethylene terephthalate (PET) technology and was the first manufacturer to succeed in qualifying PET foam as core material for the composite industry. Thanks to ArmaForm's unique combination of material and processing properties, such as outstanding fatigue endurance, elevated service temperature stability and excellent compatibility with all resin and manufacturing methods, our structural PET foam cores are widely used in composite sandwich constructions.

Whether you are looking for composite solutions in the wind energy sector, searching for lightweight core materials for building and construction, or prefer to have a choice of materials in the rail and road transport or marine sectors, Armacell offers ideal solutions. No matter the market and application, our PET Foams provides a high-performing and highly environmentally friendly alternative to PVC, Balsa, SAN, PUR or honeycomb core materials. 


Armacell took it to the next level: green PET

Armacell is the pioneer in the field of polyethylene terephthalate (PET) technology and initiated the breakthrough of PET foams as a structural core material in the composite industry. In the early days, our PET foams were made from virgin PET. Over the past decade, our global research and development team developed a process technology enabling the production of PET foam products made entirely from recycled beverage bottles. In 2010, we introduced the world’s first foam cores made from 100% recycled PET (r-PET). Today, our entire PET foam product portfolio is based on this pioneering process technology, enabling us to convert waste material into a high-quality resource and feed it back into the production cycle.

Armacell converts single-use recycled PET bottles into long-lifetime, high-value foam core materials for composite sandwich structures utilised in up to 90-metre-long wind turbine blades, high-speed train body structures, surfboards, as well as on the 24-karat gilded roof of an orthodox cathedral. Since production start in 2010, one billion recycled PET bottles used in our foam production.
