Are sealants and silicone the same?

In life and industrial production, sealants and silicone are common materials. Many people often confuse them and think that they are the same thing, but they are not. Although they have similarities in name and some application scenarios, they have significant differences in composition, characteristics and uses.

From the functional definition, sealant is a kind of viscose with sealing as the main purpose. Its main component is polydimethylsiloxane, which is combined with cross-linking agent, filler, plasticizer, coupling agent, catalyst, etc., mixed into a paste under vacuum state, and solidified into an elastomer by reacting with water in the air at room temperature. Its biggest feature is that it can fill gaps, prevent the passage of gas, liquid or dust, and play a good sealing role. Common sealants include silicone sealants, polyurethane sealants, etc., which are widely used in construction, automobile, electronics and other industries, such as sealing of building doors and windows, sealing of automobile engines, etc.
Silicone is a highly active adsorption material, the main component of which is silicon dioxide, with stable chemical properties and non-combustible. Silicone comes in various forms, including solid silicone, such as common silicone buttons and silicone kitchenware; there are also liquid silicone, which is used for potting, coating, etc. In addition to having certain sealing properties, silicone also has many other outstanding characteristics. It has excellent high and low temperature resistance and can be used in a temperature range of -60℃ to 250℃. Whether it is a severe polar environment or a high-temperature industrial production scene, it can maintain stable performance; it has good flexibility and elasticity and can adapt to various complex shapes and deformations; at the same time, silicone is non-toxic and odorless, meets food-grade safety standards, and is often used to make products that come into contact with food, such as silicone tableware, pacifiers, etc., which are safe and reliable.
It can be seen that sealants and silicone are not the same. Sealant focuses on the sealing function and is a general term for a type of adhesive with a sealing effect. The composition and types are relatively diverse; while silicone is a specific material. Due to its own characteristics, it is used in the sealing field and becomes a raw material for sealants. It is also widely used in various other fields.
