ANTI-STATIC ADDITIVE SHEETS

Static electricity is the accumulation of electrical charges on materials with low conductivity and high surface resistance
(Ω 1014 – 1018). Most plastic materials are electrical insulators and have the ability to support high static build-up. The
accumulation of static electricity on plastic sheets can cause the following problems:

Increased Dust traction, Risk of Risk of electrical
handling and which affects both electrostatic discharge causing
contamination the appearance discharge that can shock to workers
issues during and performance damage electronic and even fire and
handling, storage of plastic products components explosion
and packaging

To reduce or completely eliminate static build-up, different anti-static additives are used according to the type of material,
depending on the desired level of static protection and how long the anti-static effect should last. These additives must be well
compatible with the main polimer (PC, PMMA), have no negative effect on the transparency of the sheet and mechanical
properties. They are basically divided into two groups , ionic and non-ionic additives. Anti-static additives work by lowering
resistance and neutralizing the surrounding static field. With this functionality, static problems such as dust traction to surfaces
or electrostatic discharge (ESD) are effectively avoided.
There are two different anti-static additives.The first are permanent anti-static additives, and the second are short- and medium-
term additives. Permanent anti-static additives do not move, are immobile. Short- and medium-term additives work by moving to
the surface as the polymer matrix cools. They remove moisture from the atmosphere on the surface, reducing static accumulation
in plastic. When the air is very dry and moisture molecules are scarce, many anti-static additives are less effective.

PERMANENT ANTI-FOG

Multiwall Polycarbonate sheets, with its permanent anti-fog feature, prevent the condensed water vapor from dripping and appe-
ar as a film layer on the greenhouse cover. The drops formed by the water vapor condensing on the greenhouse covers without
antifog feature cause various diseases and burns in the plant grown as a result of the lens effect of the sunlight on the plant
and the falling of the drops. In addition, a decrease in the intensity of sunlight required for the grown plant occurs. This leads
to a loss of productivity. One of the most important features of multiwall polycarbonate sheets is that the antifog property is
permanent. It retains its anti-fog property for many years.
