Precision-manufactured specialty tapes designed for heavy mining equipment maintenance, electrical transformer winding, and high-speed SMD packaging in Erdenet.
As one of Asia's largest copper and molybdenum mining hubs, Orkhon Province demands extreme-grade electrical insulation and mechanical fixation tapes capable of enduring severe environmental dynamic loads.
Industrial operations in Erdenet experience drastic seasonal ambient temperature drops down to -40°C during winter monthes, followed by severe thermal spikes inside heavy crushing machinery, grinding mills, and step-down transformers. Standard pressure-sensitive adhesives (PSA) experience glass transition failure, losing tackiness and causing coil displacement. Our cross-linked acrylic and silicone adhesive matrices retain mechanical shear strength and flexural resilience down to -45°C without crystallization or adhesive transfer.
Erdenet Mining Corporation's ore processing plants operate continuous high-tonnage ball mills, flotation cells, and heavy haulage equipment generating continuous high-amplitude low-frequency vibrations. Micro-abrasive silica and copper dust particulates penetrate standard wire harnesses. Our woven glass fiber reinforced tapes and high-density acetate cloth tapes provide superior puncture resistance (>350 N tensile rating) and dust-sealing barriers to protect high-voltage stator coils from tracking currents and flashovers.
In high-duty electric motors and oil-immersed transformers operating in mining infrastructure, traditional tape breakdown leads to localized dielectric failure, costly plant shutdowns, and expensive coil rewinding. Jiangsu Yongjia provides specially treated flame-retardant acetate cloth and glass fiber structural tapes backed with synthetic rubber-acrylic hybrid formulations that resist varnish impregnation chemicals, prevent transformer oil degradation, and maintain 3.0 kV dielectric breakdown strength even under continuous electrical stress.

Acetate cloth tapes combine flexible cellulose acetate woven fabric with specialized cross-linked synthetic rubber or acrylic adhesives. Unlike PVC electrical tapes that become brittle and lose adhesion at sub-zero temperatures, acetate cloth remains highly conformable down to -40°C. It offers exceptional varnish absorption during transformer dipping, high dielectric breakdown voltage (≥2.5kV), and superior resistance to micro-cracking caused by extreme thermal contraction in Mongolian winters.
Our filament glass fiber tapes embed continuous longitudinal or cross-weave fiberglass yarns into a high-tack pressure-sensitive adhesive. With an extraordinary tensile strength exceeding 750 N/25mm, these tapes exhibit near-zero elongation (<3%). When used to bundle heavy power cables or secure transformer core laminations on mining machinery in Erdenet, they prevent mechanical displacement caused by constant shock loads and low-frequency vibration.
Yes. As a direct manufacturer, Jiangsu Yongjia operates high-precision automatic slitting machines capable of cutting acetate cloth, PET, and glass fiber tapes into custom widths ranging from 2mm up to 1000mm with an exact tolerance of ±0.1mm. We provide custom roll lengths, 1-inch or 3-inch plastic/paper cores, and specialized release liner backing tailored to your exact manufacturing equipment.
Heat Seal Cover Tape requires a heated sealing shoe (typically 130°C–180°C) on the SMT packaging machine to activate the thermoplastic adhesive layer, creating a permanent chemical weld with PS or PET carrier tapes. Self-Adhesive Cover Tape relies on a pressure-sensitive acrylic adhesive edge that bonds instantly at room temperature without heat. Heat seal tapes offer higher thermal stability for long-distance transport, while self-adhesive tapes allow faster setup times for heat-sensitive electronic components.
Yes. Our flame-retardant acetate cloth tape series is engineered with halogen-free flame-retardant chemical agents that meet UL94 V-0 standards. In the event of an electrical short circuit or localized arc flash inside a control cabinet, the tape self-extinguishes within seconds, preventing flame propagation along wire harnesses and protecting critical electrical infrastructure.
When stored in original moisture-proof export packaging at recommended temperatures of 15°C to 25°C and relative humidity of 40-60%, our functional tapes maintain a guaranteed shelf life of 12 to 18 months. For cold climate transport to Erdenet, our export pallets are sealed with multi-layer shrink packaging and desiccant packs to prevent condensation during transition across climate zones.
