When is the use of foil keyboards profitable?
This depends on the application. Generally, we manufacture customised keyboards from 1 piece on and our prices are reasonable. Please contact us!
Which types of foil keyboards exist and which one is suitable for my application?
How resistant against chemical influences are the foil materials used?
We use almost exclusively polyester acc. to DIN 42 115. This material is known for its excellent chemical resistance and has proven of worth for many years in almost any branch and in a
multitude of applications.
The printing is imprinted b e h i n d the decor foil and is thus very well protected.
How weather-proof is the foil material in outdoor use?
Normally, we assume that the keyboards are used indoor and only occasionally outdoor, unless the contrary is defined by the customer.
In case you assume the risk of regular ultraviolet light- or weather influences, this has to be made known already during the inquiry or development phase, as the standard materials are not suitable
or suitable only to a limited extent for these conditions.
