Analysis of application scenarios of rubber hoses of different materials: NBR, EPDM and silicone

As one of the indispensable materials in industry and daily life, rubber hose can be used in various scenarios according to its different materials. The most common rubber hose materials include NBR (nitrile rubber), EPDM (ethylene propylene diene monomer rubber), silicone, etc. This article will discuss in detail the characteristics of these rubber hose materials and their applicability in different application scenarios to help readers better understand how to choose the right rubber hose.

NBR rubber hose: the preferred choice for oil resistance

NBR, also known as nitrile rubber, is famous for its excellent oil resistance and is one of the most widely used rubber materials in industry. Nitrile rubber hose can maintain excellent sealing and durability in extremely oily environments. This is because the nitrile group contained in its molecular structure enhances the lipophilicity of rubber.

NBR rubber hose is widely used, especially in the automotive industry, mainly for oil seals and oil pipelines in fuel delivery systems. In addition, it is also widely used in machinery, chemical plants, and lubricant industries to transport various oils, coolants, etc. In the aviation industry, NBR is also particularly used for aviation fuel lines due to its oil resistance, wear resistance and moderate high temperature performance. In addition, NBR rubber tubes can also be seen in household appliances in life, such as gas pipelines, burner gas supply pipes in the kitchen, etc.

However, NBR also has its limitations, mainly degradation under high temperature and ozone exposure. Under long-term high temperature or high ozone conditions, the performance of NBR may decrease. Therefore, in high-temperature application scenarios, the use of NBR pipes should be carefully considered.

EPDM rubber tube: excellent weather resistance

EPDM, ethylene propylene diene monomer rubber, is known for its excellent anti-aging, ozone resistance, and good weather resistance. EPDM rubber tubes can resist long-term sunlight ultraviolet rays and oxidation, making them an ideal choice for long-term exposure to outdoor environments.

Another notable feature of EPDM is its excellent high temperature and cold resistance, which can maintain good performance in an environment of -40℃ to 150℃. Therefore, rubber tubes made of this material are widely used in cooling systems and brake systems in the automotive industry. In addition, EPDM also performs well in electrical insulation and is an ideal sheath material for wires and cables.

In the waterproofing of roofs and floors and sealing strips in buildings, the chemical corrosion resistance and pressure resistance of EPDM rubber tubes are also widely used in the construction field, which not only improves the durability of the building, but also ensures the stability of the structure.

Silicone rubber tube: the preferred choice for food-grade applications

Silicone, with its excellent thermal stability and biocompatibility, leads the industry trend, especially in food-grade and pharmaceutical applications. This type of rubber tube material is non-toxic and odorless, and can meet the requirements for the biological properties of materials under today’s high standards.

In food processing, silicone tubes are used to transport various liquid foods and beverages, especially in production lines with high stability requirements under high temperature conditions. The transparency of silicone makes it the most convenient observation tool in various applications, which is convenient for immediate detection and correction of possible problems in the production line. In the baby food and pharmaceutical industries, silicone tube materials are widely used in products such as pacifiers and infusion tubes due to their excellent hygiene and safety.

Silicone is also resistant to extreme climate change, showing excellent cold resistance, and still maintains its elasticity and stable performance under low temperature conditions. In special environments, such as laboratories and scientific research, silicone tubes are often used to transport strong acidic reagents such as sulfuric acid or chlorine.

However, it should be noted that silicone has low tear strength and is not suitable for use in environments with high mechanical stress. Its high cost also limits its application in some industries with high economic requirements.

Summary

Rubber tubes of different materials have their own unique properties and application characteristics. NBR rubber tubes are suitable for use in the petrochemical field due to their excellent oil resistance; EPDM rubber tubes are widely used in the automotive industry and construction due to their weather resistance and aging resistance; silicone tubes have become a must-have material in the food and pharmaceutical industries due to their excellent hygiene and high temperature stability.

Understanding the differences and applicable scenarios between these materials can help companies and individuals be more comfortable in choosing pipeline materials. Choosing the right material can not only improve the efficiency of product use, but also greatly reduce the cost of replacement and maintenance, and extend the service life of the product. Therefore, in practical applications, the reasonable selection of materials is the basic operation to ensure product quality and benefits.
