PU Hose
PU hose (polyurethane hose) has been widely used in many industries due to its advantages such as high wear resistance, flexibility, oil resistance and chemical corrosion resistance.
Features
Diversity
PU materials can be divided into hard, soft and elastomer forms, and can present different hardness, elasticity and toughness according to the formula adjustment.
Durability
It has good wear resistance, corrosion resistance and low temperature resistance, and is suitable for a variety of environments.
Lightweight and soft
PU material is light in weight and soft to the touch, and is often used in clothing, shoes and furniture.
Environmental protection
Some PU materials can use water-based or bio-based formulas to reduce environmental pollution and are more environmentally friendly than PVC.
PU hoses are strong and flexible hoses used for a variety of applications. They are made from a combination of polyurethane and other synthetic materials for strength and durability. PU hoses are resistant to oil, fuel, solvents, water, and air, making them ideal for transportation and industrial use. They also have an excellent temperature range, allowing them to be used in extreme temperatures. PU hoses are often used as hydraulic hoses, in fuel lines, or in the automotive industry. With their superior strength and abrasion-resistant material, PU hoses are ideal for many different industries and applications. They are easy to install and require minimal maintenance, making them a cost-effective solution.
1. PU pure extrusion hose
(No reinforcement layer, single-layer polyurethane extrusion molding) has outstanding performance in lightweight, flexible, chemical resistance and other scenarios due to its excellent performance of the material itself.
Construction of PU Hose
★ Tube: Extrude industrial grade, food grade or medical grade material with Polyurethane(PU)
★ Reinforcement: None
★ Temperature: -40℃ to 80℃
★ Color available: Thrasperant or by customer’s request
★ Application: Industrial automation, pneumatic tools, water and fluids, vacuum suction, metal and electronics protective covers, etc.
2. PU Pneumatic Hose
Construction
★ Material: Polyurethane (PU) inner layer + polyester fiber braided reinforcement layer.
★ Pressure range: 10~25 bar (reinforced type can reach 30 bar).
★ Temperature range: -40°C ~ +90°C (short-term +120°C).
★ Color: Common transparent, blue, black, some can be customized.
Advantages
✅ High wear resistance: 5 times more wear-resistant than rubber hose, suitable for frequent friction environments (such as factory assembly lines).
✅ Anti-bending fatigue: Not easy to crack after repeated bending, extending service life.
✅ Lightweight and soft: 50% lighter than rubber hose, easy to install and move.
✅ Oil & chemical resistance: Suitable for compressed air, lubricating oil, weak acid and alkali media.
3. PU Coiled Pneumatic Hose
Construction
★ Material: PU tube body + spiral steel wire/TPE support structure.
★ Elasticity: It can automatically rebound to its original length after stretching (elongation ratio 1:2~1:3).
★ Pressure range: 5~15 bar (low pressure type).
Advantages
✅ Automatic rewinding: No need for manual winding, saving operation time.
✅ Anti-winding: The spiral structure prevents the hose from tangling and keeps the airflow unobstructed.
✅ Space saving: The volume is reduced by 50% after shrinkage, which is convenient for storage.
4. PU Dust Hose
Construction
★ Material: PU inner layer + steel wire/fiber reinforcement + external wear-resistant coating.
★ Anti-static: Some models add conductive wire to prevent dust explosion.
★ Negative pressure resistance: Can withstand high suction (suitable for industrial vacuum cleaners).
Advantages
✅ Super wear resistance: Withstands long-term erosion of particles (such as wood chips, metal chips).
✅ Anti-static safety: Avoid dust accumulation and sparks (compliant with ATEX standards).
✅ Flexible and Anti-Crushing: Steel wire spiral support, not easy to collapse during vacuuming.
