The cost of white PET coated wires varies significantly due to application scenarios, technical specifications, and raw material market fluctuations. Currently, there is no unified standard price, but its cost composition can be analyzed through the following dimensions:

1. Core Raw Material Costs

PET Substrate: Imported PET substrate costs approximately RMB 0.9-1 per square meter, while domestically produced substrate costs approximately RMB 0.3-0.4 per square meter. Cost differences mainly stem from material purity, thickness uniformity, and temperature resistance. High-end applications typically use imported substrates to ensure stability.

Copper Conductor: Copper prices are a key factor affecting cost. As of January 2026, the LME copper price was approximately USD 13,059 per ton, a year-on-year increase of 44%. Copper conductors account for approximately 60%-70% of the cost, and fluctuations in copper prices directly impact the total cost of the wire. For example, in 0.1mm diameter Mylar wire, copper accounts for over 80% of the cost.

Coating Additives: To improve high-temperature resistance, radiation resistance, or abrasion resistance, nanoparticles or special polymers need to be added, increasing costs by approximately 10%-20%.

2. Manufacturing Costs

Process Complexity: Mylar wire for high-frequency inductors requires a 30°-45° spiral winding process, increasing equipment depreciation and labor costs by approximately 15%-25%. Medical-grade wires require biocompatibility certification, with testing costs accounting for approximately 5%-10%.

Yield Rate: In mass production, a yield rate of 80%-85% is needed to reduce costs below those of traditional copper foil. Currently, the actual yield rate is approximately 50%-60%, leading to a unit cost increase of approximately 30%-50%.

3. Cost Differences Due to Application Scenarios

Medical Equipment: ECG monitor leads must meet requirements such as resistance to disinfectant corrosion and high-frequency signal transmission, resulting in costs 50%-100% higher than ordinary wires. MRI equipment coils use double-layer F4 film Mylar wire, costing 3-5 times more than ordinary wires.

Aerospace: Mylar wire for satellite communication equipment must withstand extreme temperature differences, resulting in costs 200%-300% higher than industrial-grade products. Consumer Electronics: FFC cables are used in printers, scanners, and other devices, costing approximately 0.05-0.1 yuan per cable, but require UL certification, increasing costs by about 5%-8%.

4. Market Fluctuations and Supply Chain Impact

Copper Price Fluctuations: Copper prices are expected to rise rapidly from the second half of 2025. If copper prices remain above 100,000 yuan/ton throughout the year, wire costs will increase by 20%-30%. Companies are mitigating risks through long-term contracts and joint procurement, but small and medium-sized enterprises (SMEs) face significant cost pressures.

Alternative Material Trends: In the flexible printed circuit board (FPCB) sector, the substitution rate of PET substrates for aluminum is expected to increase from 15% to 25%, potentially reducing costs by 10%-15% in the long term. Thinner copper foil technology can reduce copper usage, but in the short term, yield issues limit cost reduction potential.
