Polycaprolactone TPU Hose & Tube

Polycaprolactone-based TPU compounds for flexible hose and tube, combining low-temperature flexibility, kink resistance and hydrolysis resistance.
Typical uses include air hoses, pneumatic tubing and fluid transfer lines that must stay flexible in cold environments.

Applications

PCL-TPU hose and tube grades are used where flexibility, durability and surface quality are required over a wide temperature range:

• Air hoses and pneumatic lines for tools, equipment and automation systems.
• Instrumentation tubing for control panels, measurement devices and fluid circuits.
• Flexible fluid transfer lines where abrasion and bending fatigue are concerns.
• Coiled hoses that must recover shape while remaining soft in cold conditions.

Typical Grades for Hose & Tube

Note: Grades and hardness are for reference only. Custom hardness, color and hydrolysis resistance can be developed for specific hose constructions.

Key Advantages

• Low-temperature flexibility for hoses used in cold climates or refrigerated areas.
• Kink resistance and elastic recovery for small bending radii and repeated flexing.
• Abrasion and cut resistance for dragging and contact with rough surfaces.
• Hydrolysis resistance for long-term exposure to moisture and humid environments.
• Smooth inner bore to reduce pressure drop and particle build-up.

Processing & Recommendations

These PCL-TPU compounds are designed for hose and tube extrusion using standard TPU lines:

• Extrusion: typical melt temperature window 185–210 °C depending on grade and line configuration.
• Drying: 80 °C × 2–3 hours to achieve stable viscosity and surface quality.
• Co-extrusion: can be used as single-layer hose or in multi-layer structures as outer or inner layer.
• Color: natural, translucent tints or opaque colors can be supplied according to your design.
