Abstract: Three kinds of retardant system, single-component Al(OH)3, Al(OH)3/Mg(OH)2, and Al(OH)3-OMMT, were applied in cable jacket material and their effects on flame retarding performance and mechanical properties were studied, When the weight ratio of Al(OH)3 and Mg(OH)2 was 1:1(phr), materials has good flame retardant property. A synergistic effect between Al(OH)3 and OMMT was confirmed by the formation of compact charred layer. Single-component Al(OH)3 also showed a significant effect on flame retarding performance.

Key words: aluminium hydroxide, magnesium hydroxide, organic montmorillonite, cable jackedt, flame retardancy
