Polyurethane hoses, Standard, PUN

Exemplary representation: Polyurethane hose

Exemplary representation: Polyurethane hose (packing)

Application examples: Polyurethane hose (does not kink)

Properties:

Polyurethane tubing is the ideal all-rounder for tubing pneumatic systems. They are kink-resistant, extremely flexible and suitable for many standard applications. In case of contact with water, we recommend the use of polyether polyurethane hoses (PUN...LE).

Advantages:

•small bending radius due to special flexibility,
•very good low-temperature flexibility and recovery properties,
•kink and abrasion resistant,
•resistance to aliphatic hydrocarbons and most lubricants,
•resistance to ageing in oxygen,
•suitable for drag chains (min. bending radius corresponds to 10x outer diameter)

Materials:

Polyester polyurethane

Temperature range:

-35 to +60 °C

Shore hardness:

95 A

Roll length:

50 m

Reference values for the pressure utilisation under temperature loading:

to +20°C: 100%, +30°C: 80%, +40°C: 68%, +50°C: 57%, +60°C: 50%
