1. Why Choose PU/TPU Over Traditional Materials?
The transition to Polyurethane is driven by its exceptional mechanical properties and compliance profiles, especially in demanding environments:

• Superior Abrasion Resistance: PU offers wear resistance 3 to 5 times higher than natural rubber or PVC, significantly extending service life when handling abrasive media such as minerals, grains, or chemical powders.
• Dust-Tight Integrity: Utilizing high-frequency welding instead of stitching ensures a 100% leak-proof seal, preventing fine dust escape and assisting in ATEX compliance.
• Chemical Stability: Excellent resistance to oils, greases, and many solvents, unlike standard rubber which may degrade or leach.

2. Regulatory Compliance and Safety
For industries involving human consumption or high-purity chemicals, material safety is non-negotiable. High-quality TPU connectors are manufactured to meet global standards:

• Food Grade Certification: Fully compliant with FDA 21 CFR 177.2600 and EU Regulation 10/2011/EC.
• Static Dissipation: Available in anti-static grades to prevent the buildup of electrostatic charges during high-speed powder flow, a critical factor in preventing dust explosions.

3. Typical Application Scenarios

• Vibrating Sifters and Screeners: The high flexibility and fatigue resistance of PU allow it to withstand constant multi-axial movement without developing stress cracks.
• Precision Weighing and Dosing: Lightweight and thin-walled PU connectors (e.g., 0.7mm) minimize force transfer, ensuring that load cells maintain high accuracy.
• Pneumatic Conveying: Designed to handle both positive and negative pressure environments, ensuring the system remains closed during high-velocity transport.

4. Technical Specifications for Selection

• Material: Ether-based or Ester-based TPU (Transparent)
• Standard Thicknesses: 0.7mm, 1.0mm, 1.5mm
• Temperature Range: -40°C to +90°C
• Connection Methods: Hose Clamps, Quick-Connect Flanges, or Custom Bolt Patterns

Conclusion:
Selecting the right flexible connection is an investment in your production line's stability. Transparent PU is particularly advantageous for maintenance, as it allows for real-time visual inspection of material flow without dismantling the line.
