Comparision of intumescent flame retardance of uncrosslinked and crosslinked LDPE/EVA/Clay nanocomposites
It is well recognized that not only flame retardancy but also flexibility, tensile properties and processability must be satisfied for the application of polyethylenene based resin as cable insulating materials. Inorganic flame retardants including aluminium trihydrate and magnesium dihydrate need to be added with large ammount to achieve good flame retardancy, which cause the deterioration of the physical properties of polyethylene1. When the ammount of nanoclay in polymer clay nanocomposites is small, remarkable reduction in the peak heat release rate (pHRR) from cone calorimetric measurements can be observed. Meanwhile, nanoclay can improve the mechanical property of composites. However, polymer clay nanocomposites shows little change in Limiting Oxygen Index (LOI) and UL 94 rating and so can not pass the regulatory tests121. They must be used in combination with other conventional flame retardant31.
