Ordering Code

1. Perfect for Humid Conditions: Solve the common aging problem of ester PU tubes in damp compressed air and high-humidity workshops.

2. Food-grade Safety Compliance: FDA certified, non-toxic and odorless, applicable for food beverage transportation and medical sanitary equipment.

3. Stable Performance at Low Temperature: Keep soft without hardening in freezing environments, ensuring stable pipeline operation in cold chains and outdoor winter conditions.

4. Customization Service: Support customized sizes, Pantone colors and cutting lengths to meet personalized project requirements.

5. Extended Service Life: Service life is increased by more than 30% compared with ordinary ester PU tubing, reducing replacement and maintenance costs.

Our high-quality ether based PU tubing is extruded from premium polyether TPU granules, designed to deliver superior performance in demanding environments that standard ester PU tubing cannot handle. As a versatile pneumatic air line, this polyether polyurethane tubing combines rubber-like flexibility and plastic durability, making it the top choice for automation, food processing, outdoor equipment and more industrial scenarios.
Unlike traditional ester-based alternatives, our ether PU tubing features outstanding hydrolysis resistance, low moisture absorption and excellent low-temperature flexibility, ensuring long-term stable performance even in humid, wet or extremely cold working conditions.

Hydrolysis Resistance: Ether molecular structure effectively resists moisture decomposition. It can work stably long-term in humid environments and damp compressed air without aging or cracking.

Microbial Corrosion Resistance: Resist fungal and microbial erosion. Compliant with FDA CFR 21 food contact standards, suitable for food processing and medical sanitary scenarios.

Low-temperature Flexibility: Maintain excellent elasticity even at -40°C. No hardening or brittle cracking, perfect for cold-chain equipment and winter outdoor use.

Abrasion & Tear Resistance: High tensile strength and bending resistance. Withstand frequent movement and torsion in automated mechanical working conditions.

Low Water Absorption: Much lower water absorption rate than ester PU tubes, preventing expansion and performance degradation caused by moisture absorption.

UV & Weather Resistance: Strong anti-ultraviolet and weatherproof ability. Suitable for outdoor exposure usage without easy aging or discoloration.
