EPDM rubber pipe basic concept and material

阅读更多

EPDM rubber hose is a high-performance synthetic rubber product. The following is a detailed introduction to it:

1. Basic concepts and materials
Definition: EPDM rubber hose, also known as EPDM rubber hose, is made of propylene, butene and a part of non-conjugated dienes through processing and polymerization.
Molecular structure: The molecular structure of EPDM rubber is very saturated, and there are no unsaturated chemical bonds in the main chain. This structure makes it have good aging resistance.
2. Performance characteristics
High temperature resistance: EPDM rubber hose can withstand temperatures up to 150°C and can still operate stably under continuous high temperature environments.
Chemical resistance: It has good tolerance to most chemicals, can work stably in a variety of complex environments, and is not corroded by media. This feature makes EPDM rubber hose widely used in chemical, food, pharmaceutical and other industries.
Aging resistance: Under sunlight, air and high temperature conditions, EPDM rubber shows extremely strong aging resistance, which can maintain the stability and service life of the material for a long time.
Mechanical properties: It has excellent tensile strength, bending performance, elasticity and wear resistance, and can withstand high dynamic stress and static stress.
Low-density filling performance: A large amount of filler can be added during the processing, which reduces costs while the mechanical properties will not change significantly.
3. Vulcanization method
The EPDM rubber tube will undergo a vulcanization step during the processing to enhance some of its properties. There are two main vulcanization methods:

Peroxide vulcanization: Products using this method have stronger temperature resistance and lower compression deformation performance, but the cost is higher.
Sulfur vulcanization: Compared with peroxide vulcanization, the cost is lower.
4. Application field
EPDM rubber tube is widely used in many fields due to its excellent performance:

Construction industry: used in water supply and drainage systems, HVAC systems, industrial pipelines, etc., its corrosion resistance and heat resistance can ensure the long-term stable operation of the pipeline.
Chemical industry: used for pipelines for conveying strong acids, strong alkalis, organic solvents, oxidants and other substances, which can effectively avoid pipeline corrosion and leakage.
Medical industry: used in infusion, atomization, negative pressure suction and other fields, its unique softness and corrosion resistance can operate smoothly in various complex applications.
Automobile and machinery industry: commonly used as steam hose, water hose, cooling hose and antifreeze hose, etc., to transport air, water, warm air, coolant and other materials.
5. Notes
Medium selection: Since EPDM is a non-polar rubber, it cannot be used to transport non-polar oil materials such as diesel and gasoline.
Installation and maintenance: When purchasing, you should understand your needs, choose the right product, and install and maintain it in strict accordance with the usage specifications to ensure the effective use and safety of the product.
In summary, EPDM rubber tube has a wide range of applications and excellent performance characteristics, and is one of the indispensable materials in many industries.
