Our High Strength Polyester Dipped Hard Cord is made of premium industrial polyester filament, manufactured through high-precision twisting and professional dipping curing process. Different from soft cords, this hard cord adopts optimized twisting density and special molding technology, forming a rigid and compact strand structure with outstanding hardness and structural stability, effectively improving the overall rigidity and load-bearing performance of reinforced rubber products.

The product boasts excellent mechanical properties, including ultra-high breaking force and stable low elongation under fixed load, which prevents stretching and deformation of rubber accessories under long-term heavy load and high-pressure working conditions. The surface is uniformly treated with dipping adhesive to form a firm bonding layer, providing superior adhesion with various rubber materials, avoiding delamination and falling off during use. All dry shrinkage force data is for reference only, ensuring stable and reliable product actual application performance.

This hard polyester cord covers diversified specifications including conventional 1100dtex series, multi-strand and large-strand structures, meeting the reinforcement demands of different heavy-duty industrial scenarios. With excellent anti-fatigue and anti-deformation capabilities, it is widely used as the core rigid reinforcement material for industrial transmission belts, heavy conveyor belts and high-pressure rubber hoses, serving as a high-performance alternative for industrial rubber reinforcement materials.
