Preparation and Characterization of Fire Retardant Methyl Vinyl Silicone Rubber Based Cable Covering Materials

Halogen free fire-retardant silicon rubber compounds for cable covering materials were prepared, using Magnesium hydroxide (MH), microencapsulated red phosphorous (MRP) as a synergist agent. Tensile Test was used to testify the mechanical properties. Limiting oxygen index (LOI) and UL 94 test were used to characterize the flammability of the developed formulations. Thermal analysis (TA) was used to characterize their thermal properties.
