In the construction and engineering field, EPDM (ethylene propylene diene monomer) and silicone rubber inflatable seals are two commonly used types of reinforced fabric inflatable seal. The following is a detailed analysis of them:
EPDM Inflatable Seal
Material Characteristics: EPDM rubber possesses excellent weather resistance, ozone resistance, chemical corrosion resistance, and water resistance, maintaining stable performance under extreme weather conditions.
Application Scenarios: In the construction and engineering field, EPDM inflatable seal are commonly used for door and window sealing, curtain wall sealing, and other applications. Their excellent weather resistance and chemical corrosion resistance allow them to remain undamaged and maintain sealing performance even after long-term exposure to outdoor environments.
Advantages: EPDM inflatable seals not only offer excellent sealing performance but also have a long service life, reducing maintenance costs.
Silicone Rubber Inflatable Seals
Material Characteristics: Silicone rubber possesses properties such as high temperature resistance, cold resistance, and is non-toxic and odorless, maintaining stable performance over a wide temperature range.
Application Scenarios: In the construction and engineering field, silicone rubber inflatable seals are commonly used in scenarios requiring temperature and humidity control or prevention of dust and harmful gas leaks, such as clean rooms, laboratories, and hospitals. Their high-temperature and low-temperature resistance allows them to adapt to different seasonal and climatic conditions.
Advantages: Silicone rubber inflatable seals not only provide excellent sealing but are also environmentally friendly and healthy, meeting the environmental and health requirements of the construction and engineering field.
Selection Recommendations:
Based on Environmental Conditions: If the construction and engineering scenario requires long-term exposure to outdoor environments and may be affected by extreme weather conditions, EPDM rubber inflatable seals are recommended. If the scenario requires temperature and humidity control or prevention of dust and harmful gas leaks, and has high environmental and health requirements, silicone rubber inflatable seals are recommended.
Based on Sealing Needs: If the sealing gap varies significantly or frequent opening and closing is required, inflatable seals can achieve sealing contact through inflation and expansion, and elastically retract after deflation to detach from the interface, adapting to gap changes. In this case, the design of the inflatable seal should be given priority, and the selection should be based on the characteristics of EPDM or silicone rubber materials.
