The difference between silicone sealing ring and silicone sealant

Silicone sealing rings and silicone sealants are both commonly used sealing materials in the industrial field, but they differ in material, performance and application areas.

Silicone sealing rings are mainly composed of silicone rubber, silicone resin, silicone oil, silane coupling agent and other ingredients. These ingredients make silicone sealing rings have excellent elasticity, heat resistance, cold resistance and chemical corrosion resistance. Silicone sealing rings can also be added with vulcanizers and color glue as needed to meet specific production requirements.

1. Heat resistance: Silicone sealing rings can be used for a long time in the temperature range of -60℃ to +200℃, and some specially formulated silicone rubbers can withstand higher or lower temperatures.

2. Cold resistance: It still has good elasticity at -60℃ to -70℃.

3. Elasticity: It can return to its original shape after being stressed and has good sealing performance.

4. Non-toxic and odorless: It is completely non-toxic and odorless, suitable for food-grade applications.

Application areas

Silicone sealing rings are widely used in waterproof sealing and preservation of various daily necessities and industrial equipment, such as fresh-keeping boxes, rice cookers, water dispensers, lunch boxes, insulation boxes, insulation boxes, water cups, ovens, magnetized cups, coffee pots, etc. In addition, it is also used in occasions that require heat resistance, such as thermos sealing rings, pressure cooker rings, heat-resistant handles, etc.

Silicone sealant has excellent resistance to high and low temperatures, chemical corrosion, UV radiation and good tensile properties. It can fill the gaps inside objects and achieve sealing, fixing and waterproofing functions.

1.Indoor applications: Silicone sealants are widely used in home decoration, furniture manufacturing, electrical appliance manufacturing and other industries. For example, they are used for sealing and fixing door and window frames, bathroom bathtubs, cabinets, and electrical appliance joints.

2.Outdoor applications: It can also be used in outdoor scenes, such as waterproofing of building exterior walls, repair, sealing and waterproofing of pavements, bridges, water conservancy projects and other building structures.

●Material: Silicone sealing rings are mainly composed of silicone rubber, silicone resin, silicone oil, silane coupling agent and other ingredients, while silicone sealant is a sealing material mixed with multiple ingredients.

●Performance: Silicone sealing rings have excellent elasticity, heat resistance, cold resistance and chemical corrosion resistance, while silicone sealants have high and low temperature resistance, chemical corrosion resistance, UV radiation resistance and good tensile properties.

Use scenarios: Silicone sealing rings are mainly used for waterproof sealing and preservation of various daily necessities and industrial equipment, while silicone sealants are widely used in indoor and outdoor building structures. By understanding the differences and usage scenarios of silicone sealing rings and silicone sealants, you can better select and use these two sealing materials to meet different engineering needs.
