Polyimide Film with FEP Adhesive
Standard No.: Q/12YJ4214
Applicable Range:
This product is the tape with ground of polyimide film manufactured by “doctor-blading process”, single surface or double surfaces covered with glue F46, and processed after drying and cutting. 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.
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 ±0.5mm, 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~0.5mm; allowable deviation is ±0.005 mm; or supply will be done according to the requirements of customer.
3. Performances of tape shall conform to the stipulations in Table One.

II Package, mark, storage and transportation
1.The adhesive material should be wound in a core of inside diameter 40mm and put it in a plastic bag and sealed and put it in a clean and dry carton.
2.There should a certificate in the box and with a mark of product name, spec, batch number, net weight, gross weight, date of production, company's name and words of ''dampproof' and 'anti shock' etc.
3.The storage period is half a year from the date of production. The material will be tested again if the storage period is over half a year. The material still can be used if test values are ok.
4.The material should be stored in dry, clean and ventilated warehouse.
5.When in transportation, the material should be protected from light, dampproof, should not be weighted or mechanically damaged.
