Other names: Rubber sleeve, Polyurethane tube, Pu sleeve etc...
Polyurethane sleeve is a versatile tube-shaped piece typically made from Polyurethane. They come in various sizes, thicknesses, hardness and lengths to fit a wide range of applications.
Main functions:
Protection: Polyurethane sleeves are widely used to protect wires, hoses, and other components from physical damage, abrasion, dust, moisture, and chemicals.
Gripping:The gripping properties of Polyurethane sleeves make them suitable for applications where a non-slip surface is needed, such as on tool handles, sports equipment, and bottle caps.
Insulation: Polyurethane sleeves can provide thermal insulation or electrical insulation depending on the material properties.
Noise Dampening: Polyurethane’s ability to absorb vibrations makes it useful for dampening noise in appliances and machinery.
Sealing: Polyurethane sleeves can create a tight seal around a joint or connection to prevent leaks or contamination.
Polyurethane sleeve performance：
1. Polyurethane sleeve have better abrasion and tear resistance than rubber sleeve, while offering higher load bearing capacity.
2. Compared to rubber sleeve, Polyurethane wheels offer superior impact resistance, while offering excellent wear properties and elastic memory.
3. Polyurethane is available in a broad Shore hardness range, depending of surface, load capacity and prefer rolling conditions, the Shore hardness will be chosen to fit the application.
4. Polyurethane sleeves have low noise, elegant performance.
Choosing for Polyurethane wheels can reduce maintenance and OEM product cost. It provides a cut down in maintenance time and failure costs while you gain the advantages of optimal rolling resistance
