slide 1: Things to Know to Choose Polycarbonate Polyester Graphic Overlay
A graphic overlay is the first and foremost thing your customers or end-users see in the
time they interact with your products. It must be long-lasting attractive as well as
functional. Thanks to the graphic overlay printing expertise. The topmost layer is called as
the Graphic Overlay that serves as the visible representation of the device’s UI panel. It can
be a single layer with high quality adhesive backing atop of a membrane switch or
normally used to activate micro switches. It is beyond doubt important to design a graphic
overlay that is both constructed effectively as well as offers an eye-catching design.
You may need custom graphic overlays for your business. A custom graphic overlay serves
as an excellent canvas for high resolution graphics for businesses to showcase their
graphics as well as logos. It not only boosts a business’s identify but also helps catching the
eyes of customers. As an owner of a business you must know that the main appeal of a
product the right materials and performance capabilities are two most important factors.
Highest quality material for graphic overlay
Graphic Overlay Materials: Polyester or Polycarbonate
Different types of materials are used but materials like polyester are normally preferred for
their durability and robustness whilst polycarbonate is not as rugged or chemically
resistant but it offers a crisp design as well. Choosing the graphic overlay material totally
depends on the end-user application and the environment in which it is used.
Therefore the material selection is one of the most important things because of the
mechanical requirements of the membrane switches. Generally polyester will survive
millions of actuations. It is solvent resistant which is good to make it perfect for the
slide 2: purpose of membrane overlays. Other materials are used by and large but they will crack
in time when the switches are pushed over and over again.
Let’s discuss two materials that are widely used one is polycarbonate and another is
polyester.
Graphic overlay materials
Polycarbonate overlays – These overlays are also called PETG or Lexan. These overlays
are very easy to die cut texture as well as print. Moreover they may show the signs of wear
after 100000 actuations. Whether the environment is subject to the chemicals a hard coat
should always be used for the purpose of protection.
Polyester graphic overlays – This type of material is generally thinner and resilient
compared to polycarbonate overlays. It shows no sign of wear after 1000000 actuations
but it has resistance power to chemicals as well as harsh environments. It is more costly
than polycarbonate. This type of graphic is especially used for military and industrial
overlays.
slide 3: Design of graphic overlays
Functionally the graphic overlay is sometimes used to protect moisture ingress into the UI
unit. Manufacturers have an essentially unlimited possibilities and wide range of design
options for the sake of customizing a graphic overlay including embossing coloring
tinting displaying windows backlighting as well as texturing.
ElecFlex can manufacture your custom graphic overlay in a variety of shapes sizes and
materials. They can ensure durability as well. Even with sub-surface graphics printing is
generally done on the inside of the overlay that is important so your overlay’s graphics
would not degrade from use or cleaning.
