| Abstract | ||
| In this present paper, experimental results on fire retardant efficacy of low-density polyethylene added with various contents ratio of egg shell were reported. The ratio of doping were (5%, 10%, 20%, 30% and 40%) wt%. The particle size of egg shell used in this research were equal or less than (125µm). Several parameters were studied like average of burning time, burning rate and percentage of burning rate. The obtained results showed that egg shell was a suitable additive to low density polyethylene and the increase of doping ratio leads to decrease in average of burning time at doping ratios above 25% which is a critical ratio. For small doping ratio the opposite is obtained hence there is an increase in time of burning. A similar results were obtained when calculating burning rate with some kind of exception at 10% doping ratio since the reduction was obvious. Also the percentage of burning time has two values positive for doping ratio equal or less than (25%). while negative value was found at doing ratio (25%) relatively to it’s pure value where negative sign explaining the mode of burning resistance of low density polyethylene. | ||
