Import 6051 Polyimide Film — Buy in wholesale FOB from Supplier in China

The 6051 Polyimide Film is a high-performance insulating material designed as a cost-effective alternative to Dupont Kapton HN, offering similar thermal, electrical, and mechanical properties. Available in thicknesses from 25μm (1 mil) to 125μm (5 mil), with widths ranging from 50mm to 1m, the film is manufactured from PMDA, ODA, and DMAC, providing a balance of flexibility, strength, and temperature resistance. Its smooth, transparent appearance and bright finish make it suitable for precision applications in electronics and electrical insulation.

This polyimide film operates across an extreme temperature range from -269°C to 400°C, maintaining dimensional stability and dielectric strength in high-voltage and high-temperature environments. Typical industry specifications include a dielectric strength of 3000-4000 V/mil, a dissipation factor below 0.003 at 1 kHz, and a tensile strength of 20-25 MPa. The film is chemically resistant, withstanding exposure to solvents, acids, and bases at elevated temperatures, and is often used in FPC substrates, motor slot liners, and transformer insulation.

Tianjin Kezan Trade Co., Ltd supplies the 6051 Polyimide Film primarily to manufacturers in the electrical, electronics, and automotive sectors, including major customers like Alstom and Moto China. The film is delivered in rolls, wound on pipe cores and vacuum-sealed in plastic bags before being packed into dry, clean boxes for protection during transit. With a shelf life of 8 years under proper storage conditions, the product is designed for long-term reliability in demanding applications.
