Product Overview

TPU Reinforced Hose is a high-performance flexible hose designed for applications requiring a combination of abrasion resistance, flexibility, pressure capability, and reliable mechanical strength. Manufactured from thermoplastic polyurethane with an integrated reinforcement layer, it is suitable for conveying air, water, oils, slurries, powders, and other compatible media depending on the selected TPU formulation.

Compared with conventional PVC hoses, TPU offers superior resistance to abrasion and repeated flexing, making this hose particularly suitable for dynamic working environments where the hose is frequently moved, dragged, bent, or exposed to particulate materials. Its relatively smooth inner surface supports efficient material transfer, while the reinforcement improves dimensional stability under internal pressure.

Different TPU hardness grades, reinforcement structures, wall thicknesses, and transparency levels can be engineered according to the application. The result is a hose that combines the processing advantages of a thermoplastic material with the mechanical performance required for demanding industrial fluid and material-transfer systems.

Materials & Construction

TPU Reinforced Hose uses thermoplastic polyurethane as the primary polymer matrix. TPU is available in different polyester-based and polyether-based formulations, allowing the material to be selected according to requirements such as hydrolysis resistance, oil resistance, abrasion resistance, flexibility, and environmental exposure.

A reinforcing layer is integrated within the hose wall to provide additional tensile strength and control dimensional expansion under pressure. Depending on the intended service conditions, reinforcement can be designed using high-strength textile or other suitable structures.

The TPU inner layer provides the primary contact surface for the conveyed medium. Its smooth bore reduces turbulence and helps facilitate the movement of fluids, powders, or granular materials. The outer TPU layer protects the reinforcement and contributes to resistance against abrasion, impact, and repeated bending.

Material hardness and wall construction can be adjusted to achieve different combinations of flexibility and mechanical strength. For dynamic applications, the construction can prioritize flex life, while pressure-transfer applications may require a higher reinforcement density.

Aplicaciones

TPU reinforced hose is widely used in industrial environments where conventional PVC hoses may experience excessive abrasion, flex fatigue, or mechanical wear. Typical applications include pneumatic conveying, industrial air lines, material handling, agricultural equipment, machinery connections, slurry transfer, and selected oil or fluid-transfer systems.

Its high abrasion resistance makes it particularly valuable for conveying dry powders, granules, pellets, dust, and other particulate materials that can progressively wear the internal wall of ordinary flexible tubing. In pneumatic conveying systems, the hose can be used for connections between fixed pipes and moving machinery where flexibility is required.

TPU’s flexibility and resistance to repeated bending also make it suitable for mobile equipment and automated machinery. Depending on the selected TPU formulation, it can provide improved resistance to oils, moisture, hydrolysis, and low-temperature exposure.

For fuels, concentrated chemicals, high-temperature media, or highly specialized fluids, material compatibility should be confirmed with the specific TPU grade before use.

TPU Reinforced Hose

Manufacturing & Quality Control

TPU reinforced hose is produced using controlled thermoplastic extrusion and reinforcement integration technology. TPU pellets are first dried and conditioned according to the material manufacturer’s processing requirements, since excessive moisture during processing can affect surface quality, mechanical properties, and dimensional stability.

The TPU material is then plasticized and extruded under controlled temperature and pressure conditions. The reinforcement layer is introduced at a controlled position within the hose wall, followed by the formation of the outer TPU layer. Precise control of extrusion speed, melt temperature, reinforcement tension, and cooling conditions is essential for maintaining concentricity and consistent wall construction.

During production, dimensional parameters such as inner diameter, outer diameter, wall thickness, and reinforcement position are monitored. Particular attention is given to the bonding and encapsulation of the reinforcement because incomplete coverage can create weak points during pressure cycling or repeated bending.

Finished hoses undergo visual and dimensional inspection. Depending on the application, additional testing can include tensile strength, elongation, hardness, pressure resistance, leakage, flex-fatigue, abrasion, and low-temperature performance evaluation.

For OEM projects, inspection criteria can be established according to customer drawings, technical specifications, or agreed quality standards. Production batches can also be identified and documented to support consistent repeat orders.

TPU Reinforced Hose

Customization / OEM & ODM

TPU reinforced hose can be engineered around the mechanical and environmental requirements of the end application. Yozonetech supports customized development for customers who require specific dimensions, pressure levels, flexibility, or material performance.

The process begins by reviewing the conveyed medium, operating pressure, temperature, bending frequency, required service life, hose dimensions, and connection method. Based on these conditions, we can recommend an appropriate TPU grade, hardness, reinforcement configuration, and wall structure.

Customization options include:

  • TPU formulation and hardness
  • Polyester-based or polyether-based TPU
  • Inner and outer diameter
  • Grosor de la pared
  • Reinforcement material and density
  • Transparent or colored construction
  • Hose length and coil configuration
  • Surface printing and identification
  • Fittings, cuffs, and end connections
  • Customized packaging and private labeling

Customers can provide drawings, existing samples, equipment interfaces, or performance requirements. Prototype samples can be produced for dimensional and application testing before mass production. This allows the final hose construction to be validated against the customer’s actual equipment rather than relying solely on theoretical specifications.

PREGUNTAS FRECUENTES

1. What makes TPU reinforced hose different from PVC reinforced hose?

TPU generally offers significantly higher abrasion resistance and better resistance to repeated flexing than standard PVC. It is particularly advantageous for abrasive material conveying and dynamic applications where mechanical wear is a major concern.

2. Is TPU suitable for conveying abrasive powders and granules?

Yes. TPU is widely used for abrasive particulate conveying because of its strong resistance to wear. The appropriate wall thickness and hardness should be selected according to particle characteristics, conveying velocity, and operating frequency.

3. Should I choose polyester TPU or polyether TPU?

The choice depends on the environment. Polyether TPU generally provides better hydrolysis resistance and can be advantageous in humid or water-exposed applications, while polyester TPU often provides strong mechanical and abrasion performance and good resistance to many oils and fuels. The actual medium and environment should be evaluated before selection.

4. Can the hose be manufactured with a specific pressure rating?

Yes. Pressure performance can be influenced by hose diameter, wall thickness, TPU hardness, and reinforcement structure. We can design the construction around a specified working pressure and required safety margin.

5. Can you develop a TPU hose based on an existing product?

Yes. OEM/ODM development can be based on a sample, technical drawing, dimensional specification, or application requirement. Our production team can analyze the construction and develop a corresponding specification for sample approval and subsequent mass production.
