Abstract: Organic fillers are not widely used in the plastic industry although their use is increasing. In this researchwe adoptedAlhaji Graecrum power as filler to modified both Hi and low-densitypolyethylene. The average particle size of AlhajiGraecrum was equal or less than 600 micrometers and the filler ratio was 35 % by weight of the polymer matrix. Flame retardant for pure and modified polyethylene in both types Hi and low density are examined. No noticeable changes made to both the average of burning time and the burning rate due to the adding of ALHAJI GRAECORUM particles. These results where explained due the fact that both LDPE and HDPE are commonly made from highly flammable hydrocarbons that burn quite readily upon ignition. The corrosion behavior of modified low and hi-density polyethylene in NaOH, HCl and Na2SO4 solution were also investigated. The weight loss as a function of dipping time in this corrosive medium was calculated. The obtained results show each corrosive medium has it is own effect of both Hi and low-density polyethylene, and each has its saturated value of weight loss.
