Guangzhou Tempered Glass Factory, Is Butyl Glue or Silicone Glue for Hollow Glass Sealing

Release time:

Oct 15,2024

We are an insulating glass factory in Guangdong, which can provide you with high cost-effective insulating glass prices. We also have excellent insulating glass processing technology and experienced insulating glass installation methods. The application effect of insulating glass is the industry standard.

In the selection of insulating glass sealing materials, butyl rubber and silicone rubber have their own unique advantages and application scenarios. The following compares the two from multiple aspects in order to more fully understand which material is more suitable.

Butyl Gum:

Sealing performance: Butyl rubber has excellent air tightness and is the best of all rubbers. It can effectively reduce the water vapor transmission rate and has a significant impact on the sealing life of insulating glass.

Thermal conductivity: Butyl adhesive has low thermal conductivity and is suitable for insulating glass with high thermal insulation performance.

Durability: Butyl rubber has good weather resistance and chemical resistance, and can be used for a long time in harsh outdoor environments.

Construction convenience: the construction process of butyl rubber is relatively simple and can be constructed manually or mechanically.

Silicone glue:

High temperature resistance: silicone rubber is stable in high temperature environment, not easy to break or embrittlement.

Weather resistance: Silicone rubber can withstand various climatic conditions, including extreme high temperature, low temperature, humidity, etc., and is not easy to age and crack.

Chemical resistance: Silicone rubber has good resistance to corrosive substances such as acid, alkali, oil and solvent.

Adhesion and flexibility: Silicone glue has good adhesion and flexibility, and can fill and seal gaps of various shapes and sizes.

2. Application Scenarios

Butyl Gum:

It is mainly used for the first seal of hollow glass, which mainly plays the role of water vapor seal. In the sealing of insulating glass, the sealing performance and thermal conductivity of butyl rubber are more critical, because it directly affects the thermal insulation performance and service life of insulating glass.

Silicone glue:

It is mainly used for the second seal of insulating glass, that is, the outer seal. Silicone glue has strong adhesion performance, solvent resistance and plasticizer performance, which can provide good external protection for butyl glue and further enhance the sealing of insulating glass.

3. Conclusion

For sealing of insulating glass:

If only from the perspective of sealing performance and heat insulation performance, butyl rubber is more suitable. Because the air tightness of butyl rubber is the best of all rubbers, and the thermal conductivity is low, it can better meet the requirements of insulating glass for heat insulation performance.

However, in practical applications, since insulating glass requires a double-channel sealing process to ensure a perfect sealing effect, butyl rubber and silicone rubber are usually used in combination. Butyl rubber as the first sealing material, mainly play the role of water vapor seal; silicone rubber as the second sealing material, mainly to enhance the structure and protect the role of the first seal.

In summary, when insulating glass is sealed, butyl rubber and silicone rubber have their irreplaceable functions. When choosing, it should be considered comprehensively according to specific application scenarios and requirements.
