Question:
How does item define antistatic in conjunction with solid plastic panels? There is considerable confusion about the terms electrostatically conducting, antistatic, conductive and conducting.

Answer:
The surface resistance of the panel is the key factor. It is this factor that determines whether or not charged particles (electrons or positrons) can land on a surface and possibly remain attached to it and then cause problems. A high degree of surface resistance will favour this scenario while low resistance will allow the charge to dissipate. The rather imprecise term "antistatic" can, therefore, be assigned varying levels of surface resistance to make it more meaningful.
< 105 ohms: 
"conducting", material cannot become charged, charges can be dissipated 
< 109 ohms: 
"conductive", material cannot become charged, charges can be dissipated
< 1012 ohms: 
"antistatic", transition area: the material will generally not become statically charged, any charges present can be dissipated to a degree
> 1012 ohms: 
"insulating", material can become charged, charges can not be dissipated

The discharge resistance of the Panel Elements which are made of solid plastic are within the antistatic range, from 109 to around 1011 ohms. This means: when friction (rubbing) is applied, there is no build-up of static charge since the charged particles are effectively dissipated at the surface. In other words, electronic components placed on the surface will not be damaged. However, if charged particles are transferred from one component that is already statically charged to a second component that is lying on the surface, the ability of the panel to dissipate this additional charge is not sufficient to prevent damage from the additional charge. For this purpose, conducting or conductive materials would have to be used as the surface.

 

Question:
A frequent question in connection with our soundproofing material (Sound-Insulating Material) product no: 0.0.440.75 regards the absorption capability above the 10,000 Hz frequency range. Do results change dramatically there?

Answer:
The answer is: No!
The high absorption rate of 95% does not change at all above 10 kHz. Note: The range audible to the human ear does not extend beyond 20,000 hertz.


 

 

Question:
During initial tests trying to cut item solid plastic worktops with water jet cutting technology large pieces broke away from the surface and the overall result was anything but satisfactory. Has anyone had experience with cutting item solid plastic worktops with water jet cutting technology or are there specific techniques to be applied?

 
Answer:
It is generally possible to cut item solid plastic worktops with water jets but it is not possible to prevent pieces of the surface breaking out.

The critical moment is when the water jet exits from the solid plastic worktops.

Also, at the beginning of the cutting process, there is considerable chance that the surface will be damaged and, as a result, the starting point of the cut should not be in the immediate vicinity of the edge, but some way away from it.
Note: It is extremely difficult to make small cut-outs or holes with the aid of a water jet.There is certainly a wide range of qualities in terms of the machines used for water-jet cutting and the experience gained with them in processing various kinds of materials. It is only possible to define the parameters specific to the particular process of cutting solid plastic worktops with a water jet in collaboration with the company doing the cutting.
As a general rule, it is possible to say that the edges cut by a water jet do not have the same visual quality as those cut by milling.
