What is the difference between silicone and rubber?


Rubber has a long history of such nouns, and silica gel is a popular saying in modern times, but what is the difference between silicone and rubber? Silicone and rubber products are widely used in people's daily life, silicone and rubber. Which one is widely used, the following Koteli comes to the difference between specific silicone and rubber:


According to its properties and composition, silica gel can be divided into two types: organic silica gel and inorganic silica gel. According to its composition, it is divided into extruded silica gel and molded silica gel. Inorganic silica gel is a highly active adsorbent material, usually with sodium silicate and sulfuric acid. The reaction is prepared by a series of post-treatment processes such as aging, acid bubble, etc. Silica gel is an amorphous substance, and its chemical formula is mSiO2.nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, and the chemical properties are not disordered. Strong alkali and hydrofluoric acid do not react with any substance. Organosilicone is an organosilicon compound, which refers to a compound containing Si-C bonds and at least one organic group directly connected to a silicon atom. It is customary to use organic groups and silicon through oxygen, sulfur, nitrogen, etc. Atom-linked compounds are also used as organosilicon compounds. Among them, polysiloxanes composed of silicon-oxygen bonds (-Si-O-Si-) are the most widely studied and widely used organosilicon compounds. One category accounts for more than 90% of the total dosage.

Silicone products: What are the wide range of applications (silicone phone case, silicone adult products, silicone pad, silicone gift, silicone daily necessities, etc.) contrast rubber no contrast products, silicone mobile phone case, breath non-toxic, long life, silicone seal ring Not resistant to high temperature: non-toxic and tasteless, long life and high temperature resistance.

The molecular chain of rubber can be cross-linked, and the rubber after cross-linking is deformed by external force, and has the ability of rapid recovery, and has good physical and mechanical functions and chemical non-disorder. Rubber is the basic raw material for the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products.

Rubber is divided into natural rubber and synthetic rubber according to raw materials. According to the form, it is divided into block rubber, latex, liquid rubber and powder rubber. Latex is a colloidal aqueous dispersion of rubber; liquid rubber is a rubber oligomer, which is generally a viscous liquid before being vulcanized; powdered rubber is processed into a powder to facilitate the preparation and processing.

Rubber products: used in industrial accessories, contrast silica gel: rubber burning is black smoke, and toxic. Contrast product: Rubber band: cheap, but not strong tensile strength, silicone rubber band: fair price, and strong tensile strength.


The difference between silica gel and rubber, in simple terms: rubber is mostly used in the industry, and silica gel products are already indispensable in different industries. Silicone silica gel is still a gel. Rubber is just as important, but the application of the two is not in the field of use.
