Summary: This study introduces a new flame retardant filler, Ni-Fe layered double hydroxides, in thermoplastic polyurethane (TPU) to improve its flame retardant properties and smoke suppression. The addition of Ni-Fe layered double hydroxides significantly reduced the peak heat release rate and total heat release of TPU, as well as decreased smoke production. The mechanical properties of TPU were minimally affected by the addition of Ni-Fe layered double hydroxides.

Summary: In this article, a novel LDH/MoS2 hybrid material was synthesized using a hydrothermal method. The LDH/MoS2 hybrid material significantly enhanced the fire safety of TPU composites by reducing the heat release rate, smoke release rate, and toxic gas emissions. The improved flame retardancy was attributed to the catalytic carbonization of LDH and the physical barrier effect of MoS2.

Summary: There is a need to enhance the fire safety of silicone foam (SiF) in aircraft and high-speed trains. A novel NiTi-layered double hydroxide nanosheets (NiTi-LDH) was prepared as an effective flame-retardant and smoke-suppressor for SiF. The results showed that NiTi-LDH improved the fire resistance of SiF and greatly inhibited smoke release. The catalytic actions of NiTi-LDH in suppressing smoke and flame retardancy were observed in both condensed and gaseous phases.

Summary: In this study, the flame retardancy of thermoplastic polyurethane (TPU) was enhanced using layered double hydroxides (LDHs) and intumescent flame retardant (IFR) through selective laser sintering (SLS) technology. The results showed that adding LDHs to the TPU composite increased the limiting oxygen index and decreased the heat release rate, smoke production rate, and carbonic oxides production. Thermogravimetric analysis indicated a favorable synergism effect between LDHs and IFR, leading to good thermal stability of the TPU/23IFR/2LDHs composite.

Summary: In this study, modified microencapsulated Mg/Zn/Al-layered double hydroxide (MLDHs) was prepared and characterized for improving the performance of silicone foams (SiFs). Various tests were conducted to evaluate the mechanical properties, flame retardancy, smoke suppression, thermal degradation behavior, morphology, and composition of SiFs with modified MLDHs. The results showed that the addition of modified MLDHs could effectively enhance the ductility and fire safety of SiFs by reducing heat release rate, total heat release, and smoke production.
