Product description

Standard No.: Q/12YJ4214-2014

1. Applicable Range:

This product is the tape with ground of polyimide film manufactured by “stretch” process, single surface or double surfaces covered with glue F46, and processed after drying and cutting. By virtue of excellent performance, the tape can replace Dupont adhesive tape F46. The tape is applicable for acting as grade H insulating material of electrical wire lapping. It takes into its shape through melting at 350-380 ℃over ten minutes.

2. 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 than1000mand the number of sections is no more than 4.

2).Width and allowable deviation of the tape is10mm±0.5mm,15mm±0.5mm,20mm±0.5mm, and25mm±1mm. Tape with other width specifications can be offered according to the requirements of customer.

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