Polymeric microcellular foams with high strength and light weight are very important for industrial applications. However, regulating their cell structure and their weak flame retardancy are problematic. We designed single-arm POSS-based ionic liquids ([bel-POSS][PF6]), and constructed hybrid composites based on ph
It especially concluded that the recent advance of phosphorus flame retardants, metal hydroxide flame retardants, nitrogen flame retardants, halogen …
Effect of CFA on flame retardancy, thermal degradation and mechanical properties of intumescent flame retardant polypropylene (PP) system (IFR-PP system) has been investigated. The results demonstrated that the intumescent flame retardant (IFR) consisting of CFA, APP and Zeolite 4A is very effective ill flame retardancy of PP.
These studies clearly show that there were no significant reactions or decomposition of the flame-retardant additive up to 5.0 V. Above 5 V, an oxidation peak was observed that could have resulted from the decomposition of …
