Silicone rubber sealing strip is a sealing product made of silicone rubber material, mainly used to fill gaps, prevent liquid or gas leakage, and isolate dust, noise, etc. It is widely used in construction, automobile, electronics, home appliances and other industries, and is highly favored for its excellent resistance to high and low temperatures, aging resistance, weather resistance and elasticity. So what are the characteristics and applications of silicone rubber sealing strips?
Main features: 1. High and low temperature resistance: can maintain stable performance in the range of -60°C to 200°C. 2. Aging resistance: anti-ultraviolet, ozone, long service life. 3. Chemical corrosion resistance: good resistance to a variety of chemicals. 4. Good elasticity: can quickly return to its original shape after compression, and the sealing effect is long-lasting. 5. Insulation: has good electrical insulation performance, suitable for the electronic and electrical industry.
Common applications: - Construction: used for sealing doors, windows, curtain walls, waterproofing, sound insulation, and heat insulation. - Automobile: used for sealing doors, windows, hoods, etc., dustproof, waterproof, and shock absorption. - Electronic appliances: used for sealing and insulation to prevent dust and moisture from entering. - Home appliances: used for door seals of refrigerators, washing machines, etc. to prevent air conditioning or water leakage.
Types: - Solid sealing strip: suitable for applications requiring high elasticity and strength. - Sponge sealing strip: suitable for applications requiring better compressibility and cushioning. - Hollow sealing strip: suitable for applications requiring light weight and good elasticity.
In short, silicone rubber sealing strips have become an indispensable sealing material in many industries due to their excellent performance and wide application.
So, what silicone oil can be used for silicone rubber sealing strips?
One. Polydimethylsiloxane (PDMS)
Properties: PDMS is a linear oligosiloxane with good fluidity, stability and excellent performance under high temperature and chemical action. It can also control its viscosity and rheological properties by changing the length and branching structure of the polymer chain.
Application: As one of the common materials for silicone rubber, PDMS silicone oil can provide the required physical and chemical properties when making silicone rubber sealing strips, ensuring the sealing strips' resistance to high and low temperatures, aging, and chemicals.
Two. Methylhydroxypolysiloxane (MQ)
Properties: MQ is a cross-linked polymer composed of methylsilane units and siloxane units, containing many hydroxyl functional groups. In the air, MQ forms a siloxane cross-linked network to form an elastic solid. It can also adjust its viscosity by controlling the hydroxyl content.
Application: MQ silicone oil also plays an important role in the production of silicone rubber sealing strips. Its cross-linking properties help to improve the elasticity and strength of silicone rubber, thereby meeting the requirements of sealing strips for sealing and durability.
For Polydimethylsiloxane (PDMS), also say Dimethyl silicone oil. You can choose the high-purity and high-transparency 201 produced by Jiangxi Baite Silicon Industry. If you have any needs, please feel free to contact us!
