The aimed of this study is prepared porous composites of silicone rubber (SR) and sodium bicarbonate (NaHCO3/SR/Chitosan) composites by mixing the medical grade liquid silicone rubber LSR with different ratios of both NaHCO3  and Chitosan (prepared from fish shells) by hand and studied their physical and mechanical properties such as tensile tests, tear resistance, hardness and compression.  The results confirmed that NaHCO3/SR/Chitosan blend mechanical properties of the composites were influenced significantly by the blowing effect of sodium bicarbonate.
