Résumé

The circular economy’s requirements are now driving up the use of recycled polymers. Nevertheless, these recycled polymers are often used through downgraded applications (1). This work aims to design high-performance recycled HDPE to replace virgin polymers in technical applications (e.g. housing, cables, urban furniture) which need highly fire-resistant materials. Various flame-retardant systems have been studied in literature. In particular, intumescent flame-retardant (IFR) system combining ammonium polyphosphate (APP) and polyamide 6 (PA 6) is known to be very effective for polyolefins (2). Furthermore, a variety of nanoparticles were assessed as synergistic agents in IFR systems (3). The current study examined the effects of an IFR system combining APP and PA6 on the fire behavior and mechanical properties of virgin and recycled PE. In addition, the effect of POSS nanoparticles as a synergistic agent (4) was also evaluated.
