What material is suitable for UV resistant sealing ring?

Uv resistant seals require the selection of materials that can maintain their performance and stability under UV radiation. Here are some sealing materials suitable for UV-resistant environments:

 

1. Silicone rubber (VMQ, Silicone)

Features:

 

Uv resistance linearity: Silicone rubber has good UV resistance and can maintain its chemical and physical properties under UV radiation.

High and low temperature resistance: Good performance in the temperature range from -60°C to 200°C.

Biocompatibility: Has good biocompatibility, suitable for medical devices.

Applications:

 

Outdoor equipment: such as solar panels, outdoor lamps, etc.

Medical equipment: such as medical devices and medical pipes.

2. Fluorosilicone rubber (FVMQ)

Features:

 

Uv resistance linearity: fluorosilicone rubber is better than ordinary silicone rubber in terms of UV resistance, and can be used in strong ultraviolet environment for a long time.

Oil resistance: Improved oil resistance and chemical resistance.

High and low temperature resistance: Good performance in the temperature range from -60°C to 200°C.

Applications:

 

Automotive industry: Seals for engines and drivetrains.

Outdoor equipment: such as solar tracking systems and outdoor sensors.

3. Polyteflon (PTFE, Teflon)

Features:

 

Uv resistance linear: PTFE has excellent chemical resistance and UV resistance, and can be used in extreme environments for a long time.

Temperature resistance: Good performance in the temperature range from -200°C to 260°C.

Non-elastomer: is a non-elastomer, often used for static sealing, but can improve its mechanical properties by adding fillers (such as glass fiber, carbon fiber).

Applications:

 

Chemical: Equipment for handling strong acids, alkalis and other corrosive chemicals.

Outdoor equipment: such as solar systems and seals in high UV radiation environments.

4. Ethylene Propylene rubber (EPDM)

Features:

 

Uv resistance linearity: ethylene propylene rubber has good UV resistance and can be used in outdoor environment for a long time.

Chemical resistance: Good water resistance, ozone resistance and chemical resistance.

High and low temperature resistance: Good performance in the temperature range from -50°C to 150°C.

Applications:

 

Construction: Used for sealing doors and Windows and building waterproof materials.

Automotive industry: for automotive door seals and radiator hoses.

5. Polyurethane rubber (AU/EU)

Features:

 

Uv resistance linearity: Polyurethane rubber has certain UV resistance properties, but it is usually necessary to add UV stabilizer to improve its durability.

Wear resistance: Excellent wear resistance and oil resistance.

Mechanical properties: Excellent performance under high dynamic stress, strong compressive deformation resistance.

Applications:

 

Industrial transmission systems: For transmission seals that require wear and oil resistance.

Outdoor equipment: such as industrial machinery and sensors.

6. Neoprene (CR, Neoprene)

Features:

 

Uv resistance linearity: Neoprene rubber has good UV resistance and can be used in outdoor environment for a long time.

Chemical resistance: Good oil resistance, ozone resistance and chemical resistance.

High and low temperature resistance: Good performance in the temperature range from -40°C to 120°C.

Applications:

 

Construction: Used for building sealing and waterproofing materials.

Outdoor equipment: such as Marine equipment and outdoor electrical equipment.

conclusion

When selecting a UV-resistant sealing ring material, it is necessary to consider the UV resistance, chemical resistance, high and low temperature resistance of the material and the specific application environment. Silicone rubber, fluorosilicone rubber, polytetrafluoroethylene, ethylene-propylene rubber, polyurethane rubber and neoprene rubber are suitable for UV resistant environment materials. It is recommended to consult a professional seal manufacturer or supplier when selecting materials to ensure that the material selected can meet the needs of the actual application.
