Abstract

This study examined the mechanical properties and the flame retardant properties of CR rubber containing inorganic flame retardant with various contents of aluminium trihydroxide (ATH, $Al(OH)_3$). The content of aluminium trihydroxide was added in 0, 30, 50, 70 and 100 phr for T1~T5 samples. It was found that increasing the amount of addition over 30 phr resulted in decreasing the mechanical properties. On the other hand in oxygen index measurements T1 sample showed a value of 38.6%, indicating the improvement of flame retardant properties showed a value of 49.7~64.2%. In case of burn test, it was confirmed that CR rubber containing over ATH 50phr content showed performance corresponding to that of first grade fire-resistance.
