What is the density range of silicone tubing, and do additives affect it?

Standard silicone tubing falls in the range of 1.10–1.30 g/cm³, though the actual figure depends on the specific compound formulation. High-density fillers such as quartz powder or certain metal oxides push density toward the upper end of that range, while low-density additives like hollow glass microspheres or plasticizers bring it down. For foamed silicone tubing, the process itself introduces air into the matrix, and density can drop below 0.5 g/cm³. Vulcanizing agents and pigments have a comparatively minor effect on density but are not negligible in precision applications. Dongguan Ruixiang Precision Silicone Products Co., Ltd. (Ruixiang) can develop custom compound formulations for medical-grade, food-grade, and industrial silicone tubing to meet specific application requirements.
