Membrane switch requirements for raw materials

- Jul 31, 2017 -

Better weatherability: The panel layer is the outer surface of the membrane switch exposed to the natural environment, the panel data to be in the natural environment conditions, one does not deformation, cracking, aging and discoloration.

Good dimensional stability: the request to manufacture the panel of the film, in the range of the temperature (usually -40 ℃ ~ 55 ℃) size size no significant change.

Elasticity: the thickness of the panel has a certain weak back, at the same time, the elastic deformation is small, can use the data to determine the rate of extension, in general, the extension rate of large, flexible deformation is also large, rebound function sent.

Excellent appearance: refers to the manufacture of panel Dongguan film switch factory film appearance smooth, glossy consistent, no mechanical damage, scratches, inclusions and stains and other appearance defects.
