Product Details：

H grade polyimide film (PI) is a polymer of imide monomers, aslo know 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.

H grade 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 tolerancem,highter 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.

Specifications：

Thickness: 25um to 250um

Width: 10mm to 1040mm

Company certificate: ISO9001, ISO14001

Polyimide is chemically stable. Polyimide does not require the addition of flame retardants to stop combustion. Polyimides in general are resistant to chemical solvents such as hydrocarbons, esters, ethers, alcohols and fluorochlorides. They are also resistant to weak acids but are not recommended for use in stronger alkaline and inorganic acid environments. Some polyimides such as CP1 and CORIN XLS are soluble in solvents, a property that has helped develop their use in spraying and low temperature cross-linking applications.
