What is Thermoplastic Hose?
Thermoplastic hoses are constructed from thermoplastic materials, which are polymers that become pliable or moldable above a specific temperature and solidify upon cooling. This unique property allows thermoplastic hoses to be flexible, lightweight, and resistant to various environmental factors. They are commonly used in hydraulic systems, industrial machinery, and other applications where durability and reliability are critical.
Advantages of Thermoplastic Hoses
1. Durability and Flexibility
Thermoplastic hoses are known for their durability, often outperforming rubber hoses in extreme conditions. Their flexibility allows for easier handling and installation, reducing operator fatigue. For instance, Gates thermoplastic hydraulic hoses are designed to convey various hydraulic fluids while exceeding SAE performance standards, making them ideal for industrial and construction applications.
2. Resistance to Chemicals and Abrasion
These hoses can withstand abrasive chemicals, contributing to their long lifespan. Swagelok’s thermoplastic hoses, for example, are engineered for high impulse pressure cycles, making them suitable for applications involving hydraulic pumps and ball valves.
3. Weight and Space Efficiency
Thermoplastic hoses are significantly lighter than traditional rubber hoses, allowing for easier transport and installation. This lightweight nature is particularly beneficial in mobile applications, such as agricultural machinery and factory equipment.
4. Non-Conductive Covers
Many thermoplastic hoses come with non-conductive covers, providing additional safety in electrical applications. Hydraulics Direct emphasizes the importance of this feature for environments where electric hazards are present.
Applications of Thermoplastic Hoses
1. Hydraulic Systems
Thermoplastic hoses are widely used in hydraulic systems due to their ability to withstand high pressure and temperature variations. Parker’s Parflex thermoplastic hoses are specifically designed for hydraulic applications, offering both hydraulic and pneumatic capabilities.
2. Fueling Applications
In the realm of compressed natural gas (CNG) fueling, thermoplastic hoses are vital due to their high-pressure resistance and safety features. Dyna Flex specializes in thermoplastic hydraulic hoses for sewer jetting and other fueling applications.
3. Food and Beverage Industry
Swagelok’s polyethylene core hoses comply with FDA regulations, making them safe for food, dairy, and water applications. This compliance is crucial for industries where hygiene is paramount.
4. Agricultural and Construction Machinery
Thermoplastic hoses provide reliable fluid transfer in agricultural and construction machinery. The Hose Shop highlights the lightweight and flexible nature of these hoses, which reduces operator fatigue during long hours of use.
