150μm polyimide film electrical insulation
,high-temperature PI film insulation
,polyimide film for electrical applications
The PI150 Series is a 150μm thick polyimide (PI) raw film manufactured by Sanfeng Win New Material (Jiangsu) Co., Ltd. It is produced through polycondensation of pyromellitic dianhydride and 4,4'-oxydianiline (ODA) in a solvent, followed by casting, imidization, and stretching processes. The film is supplied in rolls with a standard inner core diameter of 76mm rigid paper tube, featuring neat edges without damage.
It is widely used in applications requiring high thermal stability and excellent electrical insulation. Common applications include flexible printed circuit boards (FPCs), insulating tapes, motor and transformer slot insulation, electromagnetic wire wrapping, high-temperature-resistant labels, and insulating layers for electronic components. Its reliable dielectric strength and uniform thickness also make it suitable for automotive electronics, and precision electrical equipment where consistent insulation performance is critical.

Q1: Is PI150 the same as Kapton?
A: PI150 is a general-purpose polyimide film chemically similar to Kapton (DuPont trademark). It meets equivalent thermal, electrical, and mechanical specifications but is offered at a competitive price point. Always test for your specific application.
Q2: How should I store PI150 polyimide film?
A: Store in original packaging at 18–25°C and 40–70% RH, away from direct sunlight. Maximum shelf life is 6 months. Keep the roll wrapped to prevent dust and moisture absorption.
Q3. Can I get free samples?
Free samples are available, buyer only pays shipping cost.
Q4. What certifications do you have?
ISO 14001:2015.
