Wherein, described release layer A is different with the off-type force of release layer B.
Wherein, described release layer A and release layer B is polyester release film or Ge Laxin separate-type paper.
Wherein, the off-type force of described release layer A is 15gf/inch-30gf/inch, and thickness is 25um-125um.
Wherein, the off-type force of described release layer B is 5gf/inch-10gf/inch, and thickness is 25um-100um.
Wherein, the stripping strength of the described easy-to-draw bonding lamella removed to glass, SUS steel plate, PMMA plastic plate is 10
N/inch-30N/inch, its tensile break strength is 10Mpa-40Mpa, and elongation at break is 600%-1200%.
Wherein, the described easy-to-draw bonding lamella removed is thermoplastic elastomer pressure sensitive adhesive, can be rubber-like pressure sensitive adhesive, polyurethane kind
One or more in pressure sensitive adhesive or polypropylene acid lipid pressure sensitive adhesive.
Wherein, the thickness of the described easy-to-draw bonding lamella removed is 50um-200um.
The utility model compared with prior art, has following beneficial effect:
Of the present utility modelly divest two-sided fixation adhesive tape without base material is easy-to-draw, there is good stripping strength, thermotolerance and elastic stretching performance, and complete or keep in repair or reclaim not cull when removable component are peeled off making technique, do not damage again substrate (SUS steel plate, glass substrate, PMMA plate or PC plate) etc. simultaneously, the temporary fixed of electronic devices and components, lithium cell and cover plate can be widely used in, also can be used for forever pasting electronics.
