Alve-One®: Sustainable Foaming Solutions

Alve-One foaming solutions logo

Alve-One® is the new hazardous-free and eco-friendly chemical foaming agent developed by Solvay for the thermoplastic industry that meets newest and strictest market and regulatory requirements. Alve-One® is a mineral-based product, formulated with 100% safe raw materials, it will support your efforts to meet the SDGs without compromising on performance nor on competitiveness. Alve-One® is free of any hazardous SVHC substances and has been accredited as a substitute to Azodicarbonamide (ADCA).


Alve-One® Benefits Go Beyond Sustainability

The use of Azodicarbonamide (ADCA) is at risk of being restricted in Europe as it has been classified by Reach as a Substance of Very High Concern (SVHC). Moreover, ADCA decomposition residues present in the plastic foams are partially responsible for foam's bad smell and Volatile Organic Compounds (VOC) emissions that nobody wants to breathe.

Alve-One® is the safest and most efficient alternative to ADCA and expandable microspheres currently available on the market. It's the result of collaborative development with the industry and academia leading to a family of blowing agents ready to foam a wide range of thermoplastics, adapting easily to different formulations and process conditions.
