Structure and Materials
1. Baseband Material: Typically made of thermoplastic polyurethane (PU) with an internal steel wire core or Kevlar core, providing good tensile strength and dimensional stability, capable of withstanding significant tensile forces, and possessing anti-aging, anti-hydrolysis, and UV-resistant properties.
2. Green Fabric Material: Generally a high-strength elastic fabric with a certain degree of extensibility, allowing it to fit tightly against the timing belt teeth. It is bonded to the belt body through a hot-melt process, fusing the fabric surface and the teeth into a single unit.

Main Product Features and Advantages
1. Excellent Oil Resistance: This is its most prominent advantage. The green coating effectively resists the corrosion of chemicals such as lubricating oil, grease, and cutting fluid, extending its service life in oily environments.
2. High Wear Resistance and Hydrolysis Resistance: Polyurethane itself is wear-resistant, and a special formula further enhances its wear resistance and hydrolysis resistance in humid environments.
3. Good Dimensional Stability: The steel wire rope tensile layer ensures extremely low elongation of the belt under high-speed, heavy-load conditions, maintaining a constant and precise transmission ratio.
4. Good Flexibility and Smooth Operation: The polyurethane material results in a small belt bending radius and low noise, making it suitable for high-speed applications.
5. No Lubrication Required, Easy Maintenance: The meshing transmission method is clean and requires no lubrication, reducing maintenance costs and environmental pollution.
Application Areas
1. Glass Manufacturing and Processing: Used in equipment for glass edging, conveying, drilling, etc. The green fabric layer prevents glass scratches and improves positioning accuracy.
2. Packaging and Printing Machinery: Suitable for high-speed transmission systems, ensuring precise synchronization and low-noise operation.
3. Textile and Automation Equipment: Performs excellently in high-load, bidirectional transmission applications, improving system reliability.
4. Food and Packaging Industry: The fabric layer is easy to clean and meets hygiene requirements.
Selection and Usage Precautions
1. Confirm Tooth Type and Pitch: Must be perfectly matched with the pulley.
2. Understand Environmental Requirements: If the environment contains oil, water, or dust, choosing a "green" or "oil-resistant" model is wise.
3. Brand Selection: Both internationally renowned brands (Gates, Megadyne, Bando, etc.) and high-quality domestic brands offer corresponding products, ensuring quality and performance.
4. Installation Tension: A tension meter is required to adjust the tension appropriately; excessive tightness or looseness will affect lifespan and accuracy.
5. Pulley Requirements: Pulleys must have appropriate tooth profiles and precision, and are generally made of aluminum, steel, or engineering plastics.
