Selecting the optimal backing material for a cable haul-off traction belt involves matching the physical and chemical characteristics of your target cable jacket:

• Standard PVC & PE Cables: A durable 55-60 Shore A natural red rubber backing is recommended. It offers a high friction coefficient, excellent abrasive resistance, and prevents belt slippage during heavy pull operations.
• Delicate, Thin-Walled, or Shielded Cables: Low-durometer cellular sponge rubber or soft neoprene is preferred. These elastic backings absorb clamping forces, enlarging the contact area to distribute pressure evenly and prevent jacket deformation.
• High-Gloss or Medical-Grade Cables: Non-marking polyurethane (PU) or white silicone coatings are necessary to avoid dark scuff marks, carbon-black contamination, and surface scratches during high-speed extrusion.

To optimize traction stability and belt lifespan, the backing compound must also resist the continuous exposure to cooling lubricants, water baths, and extrusion temperatures typical of 24/7 B2B wire manufacturing plants.
