Flexibility and elasticity
TPU exhibits excellent flexibility and elasticity, allowing it to bend and stretch without losing its shape or structural integrity.
Durability and abrasion resistance
TPU is known for its exceptional durability and resistance to abrasion, making it well-suited for applications that require high levels of wear and tear resistance.
Chemical resistance
TPU demonstrates excellent resistance to a wide range of chemicals, solvents, oils, and other aggressive substances, making it suitable for use in various industrial environments.
Temperature resistance
TPU can operate across a broad temperature range, typically from -40°C (-40°F) to 90°C (194°F), making it versatile for use in diverse climates and applications.
Lightweight
Compared to traditional rubber or metal materials, TPU is generally lightweight, contributing to easier handling and reduced system weight.
Electrical conductivity
Depending on the specific formulation, TPU can be designed with conductive or anti-static properties, which is crucial for applications where static electricity dissipation is important.
FDA and food-grade compliance
TPU can be manufactured to meet FDA and other food-grade regulations, making it suitable for use in the food, beverage, and pharmaceutical industries.
Application of TPU Hose
The versatility of TPU hoses translates into their use across various industries:
Manufacturing
TPU hoses are integral for the transfer of chemicals and fluids during the manufacturing process.
Agriculture
They are used in irrigation systems, fertilization processes, and the transfer of pesticides.
Construction
TPU hoses facilitate the pumping of concrete, cement, and other construction materials.
Oil and gas
These hoses handle the transfer of oil products with ease, even in demanding offshore environments.
How is TPU Hose Made
There are two distinctly ways to manufacture TPU lay flat hose. Hose produced more traditional way referred to as 3-ply PU, or laminated PU. Hose produced with more technique referred to as \"extruded-through-the-weave".
3-ply or called laminated pu
3-Ply hose is actually comprised of five layers; an inner PU tube, an adhesive tube, a reinforcement jacket, an adhesive tube, and an outer PU tube. Since the adhesive tubes melt during the manufacturing process, only three layers can be seen in the finished product; hence, the name \"3-Ply.\" The manufacturing process of 3-Ply starts by pulling a polyurethane (PU) tube though the inside an adhesive tube; then, pulling these two tubes through the inside a woven reinforcement jacket. Steam is blown through the PU tube to melt the adhesive and bond the PU tube to the reinforcement jacket. The tube inside the jacket is then turned inside-out (\"turning the inside tube out\") and the process is repeated with a second PU tube and a second adhesive tube. During this procedure, moisture builds up on the reinforcement jacket and numerous pin holes are made in the outer PU tube to permit this moisture to escape.
Etw - extruded through the weae
The manufacturing process for extruded-through-the-weave (ETW) hose uses two polyurethane tubes separated by a reinforcement jacket. The PU tubes are extruded through the weave of the reinforcement jacket, melding all components into a single piece of reinforced TPU lay flat hose.
3-Ply hose could use less TPU material, the manufacturing process can keep the hose tubes as thin as they like, this results from the necessary procedure of turning the inside tube out, which becomes very difficult if the tubes are too thick. While ETW hose normally use more TPU material, and has to test hose after made, to make sure whole woven jack coved tight.
