Thermoplastic hoses are made from thermoplastic materials such as polyurethane, polyethylene, nylon, and PVC. These materials are melted and then molded into a hose using a variety of manufacturing techniques. The resulting hose is lightweight, flexible, and durable, making it ideal for a range of applications.

The thermoplastic hydraulic hose is a well-designed hydraulic hose, which is much more flexible, durable, and abrasion-resistant.

The hydraulic hoses thermoplastic can be widely applied in the medium-pressure to high-pressure hydraulic systems. And thermoplastic hoses are commonly used for mobile and industrial equipment, which need a high-pressure hydraulic working system.

Compared with the regular hydraulic hose, the thermoplastic hydraulic hose is much thinner, with the same inside diameter, so the thermoplastic hydraulic hose has much less wall thickness.

What Is Thermoplastic Hydraulic Hose Made of?

Like the hydraulic hose structure, the thermoplastic hydraulic hose has an inner tube, reinforcement, and outer cover.

Compared with the regular hydraulic hose, the thermoplastic hydraulic hose is made of Nylon plastic. The thermoplastic hose consists of an oil-resistant thermoplastic inner tube (made of Nylon), one fiber braided reinforcement, thermoplastic cover that is oil and weather-resistant.

The inner tube, touching the hydraulic fluids directly, is made of plastics, including polyamide, polyester, and even fluoropolymers. And the outer cover can protect the middle reinforced layer, which is made of the materials, such as polyester, polyethylene, and PVC.

Alternative materials like polyester elastomer or polytetrafluoroethylene (PTFE) can be added to the thermoplastic hydraulic hose to achieve the desired performance.

Some common thermoplastic materials used for hydraulic hoses include nylon, polyurethane, and polyester. These materials have excellent abrasion resistance, chemical resistance, and high-pressure capabilities, making them ideal for use in hydraulic systems.

Pneumatic Systems: Thermoplastic hoses are suitable for pneumatic systems, where air or gas pressure is a key component. They offer flexibility and lightweight construction, making them ideal for air tools and pneumatic control systems.

Chemical Resistance: Some thermoplastic hoses are designed to be highly resistant to chemicals and solvents. They are suitable for applications where the hose comes into contact with various chemicals without degradation.

Low-Temperature Environments: Thermoplastic hoses maintain their flexibility and performance even in low-temperature environments. This makes them a great choice for applications in cold climates or where low-temperature fluids are used.

Compact and Lightweight Design: Thermoplastic hoses are often lighter and more flexible than their rubber counterparts. Their compact design allows for easier routing in tight spaces.

Non-Conductive Applications: Some thermoplastic hoses are non-conductive, which means they won’t conduct electrical current. This feature is crucial in applications where electrical safety is a concern.

Aerospace and Aviation: Thermoplastic hoses are used in the aerospace industry due to their lightweight properties and resistance to high pressures, making them a preferred choice in aviation hydraulic and fuel systems.

Water Jetting and Cleaning: Thermoplastic hoses are commonly used in water jetting and cleaning applications, where high-pressure water is used for cleaning and cutting. Their ability to handle high-pressure water makes them ideal for this purpose.

Diverse Industrial Applications: These hoses find application in various industrial settings, including manufacturing, food processing, and pharmaceutical industries, thanks to their flexibility and compatibility with different fluids.

In summary, thermoplastic hoses are a preferred choice in applications where high pressure, chemical resistance, low-temperature performance, and flexibility are key requirements. They are widely used in hydraulic and pneumatic systems across various industries due to their reliability and versatility.

The Benefits of Thermoplastic Hydraulic Hose

benefits of thermoplastic hydraulic hose

There are several benefits of using thermoplastic hydraulic hoses over traditional rubber hoses:

Abrasion Resistance

Hoses are frequently subjected to various environmental stresses such as bending, scuffing, and harsh conditions. These can result in the steel braid of a rubber hose being exposed, leading to early failure. In contrast, thermoplastic hoses are engineered to be highly resistant to abrasion and do not succumb to failure like rubber hoses. This is due to the braid being integrated into the hydraulic hose material, providing superior abrasion resistance.

UV and Ozone Resistance

In addition to thermoplastic hydraulic hose abrasion resistance, thermoplastic hydraulic hoses can also offer excellent resistance to ultraviolet (UV) light and ozone. This makes them suitable for use in outdoor applications where the hose may be exposed to direct sunlight and other environmental elements.

UV light can cause rubber hoses to degrade and become brittle over time, while ozone can cause cracks and holes to develop in the hose. Both of these can lead to hose failure and leaks, which can cause significant downtime and repair costs.

Thermoplastic hoses, on the other hand, are designed to be highly resistant to UV light and ozone, which helps to extend the life of the hose and minimize the risk of failure. This makes them a reliable and cost-effective option for outdoor hydraulic applications, such as those in agriculture or construction.

Lower Cost Than Rubber Hydraulic Hose

In some cases, thermoplastic hydraulic hoses can be more cost-effective than traditional rubber hoses. This is due to several factors, including:

  1. Material costs: Thermoplastic materials used in hydraulic hoses can be less expensive than the materials used for rubber hoses.
  2. Production costs: The production process for thermoplastic hoses is often more efficient and streamlined than that rubber hoses, which can help to reduce costs.
  3. Lower weight: The lighter weight of thermoplastic hoses can help to reduce shipping costs and make them easier to handle, which can help to reduce overall costs.
  4. Increased durability: The increased durability of thermoplastic hoses compared to rubber hoses means they may last longer and need fewer replacements, which can help to reduce costs over time.

Lighter Compared with Hydraulic Hose

Another advantage of using thermoplastic hoses is their lightweight construction. These hoses are typically much lighter than other types of hoses, which makes them easier to handle and transport. This can be especially important in applications where the hose needs to be moved frequently or where weight is a concern.

The lighter weight of thermoplastic hydraulic hoses compared to rubber hoses is due, in part, to the type of reinforcement used. Traditional rubber hoses are often reinforced with steel braiding, which adds strength and durability but can also add weight to the hose.

Thermoplastic hoses, on the other hand, use a variety of reinforcement methods that are lighter and more flexible, including braiding made from high-density polyethylene (HDPE) or aramid fibers. This lighter reinforcement allows the hose to maintain its strength and stability while reducing its overall weight.

Thermoplastic Hydraulic Hose Applications

Thermoplastic hydraulic hoses are a type of hose used in hydraulic systems to transmit fluid power. They are made from thermoplastic materials such as nylon, polyurethane, and PVC, which offer several advantages over traditional rubber hoses. Some common applications of thermoplastic hydraulic hoses include:

  1. High-pressure systems: Thermoplastic hoses can withstand higher pressures than rubber hoses, making them ideal for high-pressure hydraulic systems such as those used in construction machinery and mining equipment.
  2. Chemical resistance: Thermoplastic materials are resistant to a wide range of chemicals, making them suitable for use in applications where the hydraulic fluid may be corrosive or abrasive.
  3. Low-temperature applications: Thermoplastic hoses remain flexible at low temperatures, making them ideal for use in cold environments such as snowplows and freezer rooms.
  4. Compact and lightweight: Thermoplastic hoses are lighter and more flexible than rubber hoses, making them easier to handle and install in tight spaces.
  5. Food and beverage industry: Thermoplastic hydraulic hoses are FDA approved, making them suitable for use in the food and beverage industry where they can be used in food processing and packaging equipment.

Thermoplastic hydraulic hoses offer a range of benefits over traditional rubber hoses, making them a popular choice in a variety of applications.
