What is U-shaped foam rubber gasket?

U-shaped foam rubber gasket is a product made from three main components: zinc, EPDM rubber, and foam rubber. The zinc component is used to provide hardness and stability to the gasket, while the EPDM rubber provides elasticity and weather resistance.

U-shaped foam rubber gaskets have a U-shaped profile and are designed to create a tight seal between two surfaces. The foam rubber inside the gasket helps create compression and resilience while providing flexible elasticity to adapt to imperfect surfaces. The outer covering is made from EPDM rubber, which helps protect the gasket from the impact of weather, UV rays, and other environmental factors.

U-shaped foam rubber gaskets are commonly used in various industries, including automotive, shipbuilding, construction, electronics, and other applications. They are often used to create tight seals, prevent dust and water ingress, or provide resilience in applications that require pressure and temperature variations.

Comparison of features between EPDM foam rubber and EPDM rubber

Both EPDM foam rubber and EPDM rubber are made from EPDM synthetic rubber, but there are some differences in their features and applications. Here are some comparisons of the features between these two types of rubber:

1. Structure:

• EPDM foam rubber: It has a foamed structure, meaning it has air pockets inside forming a cellular foam structure. This gives EPDM foam rubber insulation properties, good resilience, and better compressive load-bearing capabilities.

• EPDM rubber: It has a solid structure without air pockets inside. EPDM rubber has higher elasticity and hardness compared to EPDM foam rubber.

2. Physical properties:

• EPDM foam rubber: It has good water resistance, weather resistance, ozone resistance, and UV resistance. EPDM foam rubber also has the ability to withstand high temperatures and temperature variations.

• EPDM rubber: It has high elasticity, high hardness, and the ability to withstand temperatures ranging from -50°C to 150°C. It also has weather resistance, ozone resistance, and chemical resistance.

3. Applications:

• EPDM foam rubber: It is commonly used in insulation, soundproofing, vibration damping, door gaskets, air sealing, contact pads, and applications that require resilience and load-bearing properties.

• EPDM rubber: It is commonly used in high-temperature applications, door and window seals, pipe gaskets, liquid sealing gaskets, impact-resistant parts, and applications that require elasticity and chemical resistance.

However, there can also be combinations or layered configurations between these two types of rubber to harness the benefits of both features. The choice of suitable rubber depends on the specific requirements of the application. If the application requires insulation properties, good resilience, and load-bearing capabilities, EPDM foam rubber may be a good choice. On the other hand, if the application demands high elasticity, temperature resistance, and chemical resistance, EPDM rubber is often used

Furthermore, both EPDM foam rubber and EPDM rubber have good weather and ozone resistance, making them suitable for outdoor applications. However, before choosing a rubber type, it is necessary to consider specific technical requirements and environmental conditions to ensure the suitability and effectiveness of the product.

In summary, EPDM foam rubber and EPDM rubber have their own features and advantages, depending on specific requirements and applications. Researching and selecting the appropriate type of rubber will ensure the performance and reliability of the product during use.
