Nitrocellulose (NC) is one of the most widely used energetic polymers, particularly in nail polish, paints and chemical propulsion applications. Neat nitrocellulose fibres can only be transformed into a rigid material whose thermal decomposition occurs before the material reaches thermoplasticity. Therefore a plasticizer like camphor needs to be added to make nitrocellulose more flexible by reducing its working temperature. Celluloid, one of the oldest thermoplastic, is a mix of NC and camphor as a plasticizer. This material is no longer employed as a commodity plastic, but it has recently received a renewed level of interest for combustible casing applications. In this instance, the inherent combustion properties of celluloid are further enhanced by foaming the material. This work aims at evaluating novel celluloid formulations where the camphor is being replaced by other plasticizers. The effects of these new plasticizers on the mechanical and combustion properties of the resulting foamed has been investigated. Four camphor surrogates were selected among chemicals being used to plasticize low molecular NC found in cosmetic products. The formulations were first prepared by a solvent assisted batch mixer process in a horizontal internal mixer before being finalized into sheets using in a twin roll mill. Mechanical properties of foamed and non-foamed materials were determined by tensile tests. On non-foamed sheets, the results show that at least one plasticizer provides better properties than the formula with camphor. The compatibility and thermal stability of the novel plasticized NC formulations were also determined from DMA, DSC and TGA measurements. The effects of these novel plasticizers on the foamability of the material was found to be significant and they will be assessed with further investigations.
