Widely Used Polyimide Pi Film with Excellent Properties
Polyimide (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.
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. 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 trading company or manufacturer ?
We are a manufacturer, We have our own 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 same as the sample sent to me before?
We kept another same sample and marked on company when we sent to customer. So our production will be based on and also we will test the product before shipment.
Q4: Which package do you use?
Package is important part to avoid goods breaking in transportation. We will choose suitable packing depend on materials.
Package&Storage:
