Polyimide (PI) is a polymer of imide monomers, aslo know as heat resistant film or higher temperature film. With their high heat-resistance, polyimide enjoys varied purposes in roles demanding rugged organic materials. Polyimide film is perfect for insulating circuit boards, large temperature powder coating and transformers producing.
Polyimide film gives outstanding electrical, thermal, bodily and chemical properties over a wide temperature range amongst -269ºC (-452ºF) and 400ºC (752ºF) producing them superior for electrical insulation applications. Polyimide film can be laminated, metalized, punched, formed or adhesive coated. BOPI movie has far better thickness tolerancem,highter physical, chemical,and electrical houses. It is the recommended option for applications that need an all-polyimide film with an excellent stability of qualities in excess of a wide assortment of temperatures.
we can provide the two common and custom polyimide film answers for a client based on their requirements.

Q1:Are you investing organization or company ?
We are a producer, 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 check the item ahead of shipment.
This autumn: Which package do you use?
Package is important part to avoid goods breaking in transportation. We will choose suitable packing depend on materials.


Packed in rolls and in carton store at area temperature keep away from fire. The storage interval is twelve months.
