Product Description

The film preparation method is as follows: polyamide acid solution flow forming film, stretching, high temperature imide.Thin film is yellow transparent, relative density 1.39 ~ 1.45, has outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties, can be used in 250 ~ 280ºC air for a long time.The vitrification temperatures are 280ºC(Upilex R), 385ºC(Kapton) and above 500ºC (Upilex S), respectively.The tensile strength is 200MPa at 20ºC and greater than 100MPa at 200ºC.It is especially suitable for flexible printed circuit board base material and insulation material of various high temperature resistant electric motor.

Q1:Are you a 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?
A4 size Samples & Small rolls 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.

Package&Storage:

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