Alcohol Corrode The Silicone Rubber Seal Or Not

Apr 09, 2018


                                        Can we use silicone rubber seal to seal the alcohol liquid?

      Will alcohol corrode the silicone rubber seal? A silicone rubber seal is used to seal alcohol, and there will be no reaction between them. The silicone rubber sealing strip is introduced as a kind of high active adsorption material. The silica gel is a highly active adsorption material, usually with sodium silicate and sulfuric acid, and it is made by a series of post-processing processes, such as aging and acid bubbles. Silica gel is an amorphous substance whose chemical molecular formula is mSiO2.nH2O, insoluble in water and any solvent, nontoxic and tasteless, stable in chemical properties, It is not to react with any substance except strong alkali and hydrofluoric acid. Alcohol is a colorless, transparent, volatile, combustible and nonconductive liquid. When alcohol is 70%, it has a strong killing effect on bacteria. Therefore, for some only FDA certification, medical silicone rubber seal, generally used in high temperature with alcohol or physiological saline to be sterilized and preserved. Therefore, it can be seen from the above description that alcohol will not corrode silicone rubber seal, and will not cause any damage to silicone rubber seal.

       Silicone rubber is more heat-resistant than ordinary rubber. It can be used almost forever at 150 degrees without change of performance; it can be used for 10000 hours at 200 degrees; it can also be used for a period of time at 350 degrees.

      Ordinary rubber degrades rapidly under ozone generated by corona discharge, while silicone rubber is not affected by ozone. And for a long time under ultraviolet and other climatic conditions, its physical properties vary little. Anti aging, corrosion resistant, silica gel itself has strong inertia.
