Polyurethane (PU) Flexible Tubing Polyurethanes 3 specific materials - ester, ether and food-grade ""crystal"" - offer excellent flexibility and outstanding use in a wide range of applications. The tubing allows for 50% space reduction when compared to semi-rigid tubing. There are 3 material grades: • PU ester - for pneumatic applications • PU ether - no water absorption • PU ether food-grade ""crystal"" - chemical resistance superior to PU ether Features and Benefits • Excellent mechanical properties • Optimal bend radius • Unsurpassed abrasion resistance for a single layer tubing • UV-resistant • Superior vacuum capability due to surface hardness • Good vibration absorption • Large choice of colours to facilitate circuit identification • Silicone-free • Consistent tensile strength for optimum longevity Product Application Information • Factory automation • Miscellaneous manufacturing • Food and beverage • Vehicle assembly facilities Used for compressed air, fluid conveying and standard pneumatic applications requiring rapid cycles. Also suitable for vacuum applications, water and high humidity (PU ether).
