Import Dipped Soft Or Stiff Polyester Cord — Buy in Bulk from Supplier in China

The Dipped soft or stiff polyester cord from Zhucheng Zhonghe Industry & Trade Co., Ltd. is manufactured from 100% high-tenacity polyester filament, coated with a phenolic or rubber-based dip compound to enhance adhesion in composite structures. The cord is available in two variants: soft (low stiffness, high flexibility) and stiff (high modulus, low elongation), with diameters ranging from 0.8 mm to 3.0 mm. The dip coating is applied uniformly to ensure consistent bonding in rubber matrices.

The soft variant is typically used in tire carcasses and flexible hoses where conformability to curved surfaces is critical. The stiff variant is preferred in V-belts and timing belts requiring high tensile strength and dimensional stability. The base filament has a denier range of 600 to 2200, with a typical tenacity of 7.0 to 8.5 cN/dtex. The dip compound is formulated for compatibility with natural and synthetic rubbers, meeting standard adhesion test thresholds for industrial rubber products.

Orders are fulfilled in spools of 50 kg or 100 kg, wound on steel or plastic cores. The standard trade terms are FOB Qingdao, with lead times of 20 to 25 days after order confirmation. Minimum order quantities are negotiable but typically start at 500 kg per size and variant. Packaging includes moisture-resistant polyethylene wrapping and wooden crates for bulk shipments. Buyers should specify the dip type, denier, and elongation at break when placing orders.

Zhucheng Zhonghe Industry & Trade Co., Ltd. is based in Suishaling Village, Xinxing Town, Zhucheng, Shandong Province, China, with operations focused on textile-reinforced industrial cords. The supplier is classified as harbor-tier, indicating verified factory location and export documentation compliance. No information is provided on company history, workforce size, or production capacity. The listing does not mention certifications, client names, or third-party testing results.

The supplier’s response rate is zero and average response time is untracked, suggesting limited buyer communication infrastructure. Product quality appears to follow standard Chinese industry practices for dipped polyester cord, with batch-specific filament sourcing and dip viscosity controls. Buyers should request filament origin reports and dip compound composition data. The supplier does not claim ISO or ASTM compliance, so independent testing is advised for critical applications.
