Flame retardant presentation of dicumene
When dicumene is used as a synergist of flame retardancy, the halogen chain can be transferred by generating free radicals. And when the external temperature rises, it can promote to generate the halogen free radical to achieve the effect of flame retardance.
In addition, dicumene quantity will not impact the tensile strength of the system greatly, but the elongation at break of the system decrease with the increase of amount of dicumene.
When the amount of dicumene is up to 1.2, it can have both good flame retardancy and the tensile properties. Therefore, considering the influence of factors such as performance and cost, the amount of dicumene will be controlled in 1~2 parts, which not only can greatly improve the elongation at break, but also improve the flame retardancy.
