Import Fiber Glass Cord — Buy in Bulk from Supplier in China

Fiber Glass Cord from YUSHENG ENTERPRISE LIMITED is a reinforced textile strand engineered for use in rubber composite belts, particularly timing belts in automotive and industrial applications. The cord is produced using glass filaments treated with a proprietary dip coating to ensure adhesion to rubber matrices such as CR, EPDM, and HNBR. Available grades include EC9 110, 1/3, 1/6, 1/11, 1/13, 3/15, and ECG 150, 3/11, 3/13, each denoting filament count, twist direction, and construction density. These designations reflect standardized industry nomenclature for glass cord reinforcement, not proprietary labels.

The glass filaments are drawn from high-silica content fibers with a tensile strength typical of 1.8 to 2.2 GPa, and the dip coating enhances compatibility with elastomers without compromising thermal stability. The cord retains structural integrity up to 300°C and resists degradation from oils, ozone, and UV exposure under normal operating conditions. It does not contain halogenated flame retardants; its fire resistance stems from the inherent non-combustibility of glass. The twist configuration and filament count determine flexibility and belt fatigue life, with finer counts like 1/13 used in high-precision timing applications.

This cord is purchased by manufacturers of automotive timing belts, conveyor systems, and industrial drive belts, primarily in Europe, North America, and Southeast Asia. Buyers typically source it in spools of 500m to 1000m, wound on plastic or metal cores, and packaged in cartons of 10 to 20 spools. Minimum order quantities are not stated in the listing and must be confirmed directly with the supplier. Delivery is usually FOB Qingdao or Shanghai, with lead times ranging from 15 to 30 days depending on order volume and current production scheduling.

YUSHENG ENTERPRISE LIMITED is based in Wei Fang City, Shandong Province, China, and operates as an organic-tier supplier with voyage-level trust verification. The company specializes in textile reinforcements for rubber composites, with a focus on glass cord for timing belts. Its profile does not state years in business, annual production volume, or client names. There is no verified certification data listed, and response metrics are not available, indicating limited buyer interaction on the platform.

The supplier does not claim ISO certification, export history, or R&D capacity. Product development appears to follow industry-standard formulations for glass cord, with no indication of proprietary coating technology. The listing confirms only production capability and basic product compatibility with CR, EPDM, and HNBR rubbers. Buyers should treat this as a manufacturer with documented output but unverified scale or quality systems.
