How to select varieties of thin panel material?
Suitable for the production of film material layer panel, according to their kinds, from the contents of the
above, we know that often PC,PET of three; its surface state there sand surface (3 out
semi-permeable membrane) and smooth (transparent membrane) of the points.
Physical properties of PC materials and chemical characteristics of composite indicator is better, its
adaptation to printing ink is also more extensive membrane switch panel is the most common application
of the material layer.
PC material is smooth sand surface with distinction, choice of materials like sand
surface ground yes because the membrane switch to use multiple electronic machine Chan Pin, as a
control Kongzhixitong of Mianban Bu Xi Wang by light harassment, which form the surface of sand
surfaceshowed only diffuse form, does not produce bright reflection; the same time, disturbance of the
surface was sand-like,with the scratch masking effect,contrast,smooth material not have the above characteristics.
But as a smooth material, once in the back of the print,the color will be even more colorful,the decorative
touches required strong and because they do not need frequent occasions, often glossy
materials selection panel, or for some display area, such as LCD liquid crystal display of special needs to
consider more favorable selection of smooth material.
PVC film material at a lower price, about one half of PC material, when the production of civilian popular
type of product, if you choose PVC material, can reduce production costs and better scalability PVC
material,can use cold processing threedimensional graphic.
Smooth PVC sheet thickness generally 0.5 mm or more, two are PET or water
tape to protect the majority for the production of decorative panels; sand surface of the
PVC material thickness of 0.3 mm below normal, it's generally Length sheet supply, no roll.
General performance for PET film can be replaced by PC film, so the material used for the panel is not too
much, except in certain special occasions, such as the insulation, resilience, solvent resistance, etc. can
not be met by other films cases, only a small number of applications.
PET film surface state, generally smooth transparent membrane, a few things have sand surface of the
products, companies such as Japan Kimoto KB products, but very fine sand surface, similar to a kind of
desert light of the surface layer, the surface of PET desert surface was light, it is not as PC as the way
through the machinery from the sand surface of the roller in the machine to get rolling process, which also
determines its surface is less than PC's sand surface as clear as the British Autotype company texture of
the polyester film is a coating film. Length of the coated membrane sheet over to the supply, the price is
higher than the sand surface PC is about 3 to 5 times, the user is bound to be targeted, from careful
Our membrane switches are widely used in :
