Armacell (Luxembourg), a global provider of flexible foam for the equipment insulation market and engineered foams, launches ArmaPET Struct GRX, a recycled PET (rPET) foam core technology that improves efficiency and sustainable sandwich structure production.

Entirely made from recycled plastic bottles, ArmaPET Struct GRX offers an optimized resin uptake process, further improving weight and cost. Its thermal and dimensional stability safeguards high-quality production, while high fatigue resistance ensures long-term performance and low lifetime maintenance. ArmaPET Struct GRX also boasts a more homogenous and finer cell structure compared to previous generations resulting in enhanced shear properties. 

Extensive testing conducted by Armacell proves that ArmaPET Struct GRX exhibits comparable or even better mechanical performance to its predecessors — for example, its adjusted foam recipe delivers an increase of up to 30% in shear properties. It is available in a wide density range from 100-250 kg/m3.
