The PU Core Belt is a high-performance transmission belt featuring a reinforced composite structure designed to provide high tensile strength, excellent wear resistance, dimensional stability, and reliable operation.

Construction

- Outer Layer (PU): Made from Polyurethane (PU), offering excellent elasticity, abrasion resistance, and mechanical durability.

- Core Layer (Core): Reinforced with high-strength steel cords or specialized synthetic fibers, helping maintain dimensional stability and prevent excessive elongation or breakage under high loads.

- PU Core belts are widely used in power transmission and light-duty conveyor systems, thanks to their excellent elasticity, tensile strength, durability, and reliable anti-slip performance. The PU surface provides good traction and is available in various sizes to meet different application requirements.

Key Advantages

1. High Tensile Strength & Low Elongation
The reinforced core provides high tensile strength and excellent dimensional stability, helping maintain consistent belt tension and synchronized operation during continuous running.

2. Excellent Wear & Chemical Resistance
High-quality Polyurethane provides excellent resistance to abrasion, oils, grease, and many common chemicals. It also offers better aging resistance than conventional rubber belts.

3. High Transmission Accuracy – For Toothed PU Core Belts
For toothed PU Core belts, the precisely molded tooth profile provides accurate engagement with the pulley, minimizing slippage and ensuring reliable synchronous transmission. This makes them suitable for automated packaging and product sorting systems.

4. Smooth & Quiet Operation
The optimized material structure helps reduce friction and operating noise, allowing conveyor and transmission systems to run smoothly while improving energy efficiency.

5. Suitable for Hygiene-Sensitive Applications
The PU surface is easy to clean and less prone to dust accumulation and surface deterioration compared with conventional rubber materials, making it suitable for applications requiring high standards of cleanliness, including food processing, pharmaceutical, and electronic component manufacturing.
