Polyimide (PI) is a polymer of imide monomers, also known as heat resistant film or high-temperature film. With their high heat resistance, polyimide enjoys diverse applications in roles demanding rugged organic materials. Polyimide film is ideal for insulating circuit boards, high-temperature powder coating, and transformers manufacturing.

Polyimide film provides excellent electrical, thermal, physical, and chemical properties over a wide temperature range between -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation applications. Polyimide film can be laminated, metalized, punched, formed, or adhesive coated. BOPI film has better thickness tolerances, higher physical, chemical, and electrical properties. It is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.
we can provide both standard and custom polyimide film solutions for a customer depending on their needs.

FAQ
Q1:Are you a trading company or manufacturer?
We are a manufacturer, We have our workshop producing electrical insulation polyimide film.
Q2: Can you send samples for testing?
A4size Samples are free supplied, customers just need to pay a litter shipping charge.
Q3: How can you guarantee the quality of mass goods is the same as the sample sent to me before?
We kept another same sample and marked it on the company when we sent it to the customer. So our products will be based on and also we will test the product before shipment.
Q4: Which package do you use?
The package is an important part to avoid goods breaking in transportation. We will choose suitable packing depending on the materials.

Packed in rolls and cartons; store at room temperature; avoid fire. The storage period is 12 months.

Note: Above values are the accumulative typical ones by the recognized testing method, but, to ensure you select our products properly, please refer to the above specification and test the samples based on your using purpose or feel to contact us for more details...
