Abstract
The aim of this research to use extracted natural material from waste product of Okra as blowing material by simple method for production sponge rubber. The sample of rubber was prepared with adding different percent from extracted material of waste product of Okra (0-25)% to study the effect of this material on properties of natural rubber. When we added different percent from blowing material that extracted from plant of Okra , we get productions of cells inside the sample due to degrade blowing material, release gases and get sponge rubber causes decrease specific gravity ( from 0.997 to 0.982) , tensile strength (from 13.295 to 7.881)MPa and modulus of elasticity (from 2.745 to 1.512)MPa. This mean is extracted material of waste product of Okra is suitable to use as blowing material to get sponge rubber and this work exists with a good replacement for synthetics blowing materials avoiding their toxicity and their highly cost.
