The aim of this research to use extracted natural pigments which extracted plants such as chlorophyll as plasticizer and stabilizer material by simple method. The sample of rubber was prepared with adding different percent from chlorophyll pigment (0-25)pphr to study the effect of this material on properties of natural rubber. When we added chlorophyll pigment, we fined chlorophyll act as plasticizer thatinteract between rubber chains and decrease interaction molecular forces that decrease specific gravity (from 0.997 to 0.986), tensile strength (from 13.295 to 8.384)MPa, modulus of elasticity (from 2.745 to 1.312) MPa. This mean is chlorophyll pigment is doing as lubricant material to facility the moving of molecules chain one on anther and act as stabilizer that protect rubber from UV light because itabsorbed UV light and transmit it to no harm heat .Therefore this work exists with a good replacement for synthetics plasticizers and stabilizers materials avoiding their toxicity and their highly cost.
