Natural rubber (NR) in a typical semi-efficient vulcanization system was modified with flame-retardant additives such as bromo derivative of phosphorylated cashew nut shell liquid, antimony trioxide and alumina tri hydrate (ATH). Improvement in the flame retardancy of the vulcanizates was shown by the progressive increase in Limiting Oxygen Index with the concen tration of ATH. Besides, the smoke density and the smoke release rate were reduced substantially in the presence of 100 phr of ATH in the vulcanizate. Thermogravimetric analysis showed higher activation energy for decomposi tion and higher yields of decomposition residue for the ATH-filled NR vulcanizates. Also, the vulcanizate modified with the flame retardants showed improvements in tensile and tear strengths in presence of 50 phr of the filler.
