Guillaume Capon, CREPIM France, presented the GREEN-FR project from the common laboratory SERFBIO (CREPIM + UPJV, with French public funding) which aims to synthesise and assess the fire performance properties of bio-based PIN flame retardants in various matrices such as polyurethane and polypropylene.
A bio-based ethylene glycol extracted from bio-industry by-products (sugar, itol) was used to study the FR effects of molecular carbon structures (aromatic rings, heterocyclic or not), phosphonate, and other phosphorus and nitrogen structures. Factors tested included processing, water uptake, blooming, durability and fire performance. The project is now looking for industry partners to scale up to commercial testing and production.
