Polyimide Film with FEP Coating on Single Side

Polyimide Film with FEP Coating on Single Side
Product Detailed
Thickness:0.05mm Width:8mm Length:2000m ID:40mm OD:280mm

This product is made from polyimide film painted with F46 adhesive on single surface or double surface and cut after drying. It is applied as insulation material for electrical wire winding, which is molded through melting at the temperature of 350-380°C for half an hour.

I.  Technological requirement:

1. Appearance: The tape is dry, smooth as well as free from any bubble or impurity, etc.

2. Dimension:

1) Length: The length of every roll of tape is not less than 300 m and the number of sections is no more than 4.

2) Width and allowable deviation of tape is 10mm ±0.5mm, 15mm ±0.5mm, 20mm ±1mm, and 25mm ±1mm. Tape with other width specifications can be offered according to the requirements of customer.

3) Nominal thickness and allowable deviation: thickness range 0.03mm --- 0.10mm; allowable deviation is ±0.005 mm ---±0.006 mm; or supply will be done according to the requirements of customer.

3. Performances of tape shall conform to the stipulations in Table One.
