Sigma’s Atmospheric Plasma (APT) system is designed to provide superior quality surface treatment on a broad variety of substrates that includes, fabric, films, foams, powders, paper and foils. Sigma’s APT system incorporates both ceramic and metal electrodes, powered by a mid frequency generator with PLC controlled gas mass flow system, for controlling the plasma gas through the electrodes. One or more plasma gasses can be fed into the treater, alone or in combination with functional monomers. Sigma has developed large scale systems for converting functional monomers into vapors.

The atmospheric plasma systems shown above can opearate in one or more of the following operating modes:
Atmospheric Plasma: Using helium/argon and reactive gases for applications that require uniform treatment (in contrast corona which involves streamer type discharges)
Chemical Corona (a pseudo-plasma discharge): Created by feeding reactive gases into the treater, without the use of He or Ar. This is a low cost alternative to plasma for obtaining unique treatment of surfaces without the use of high cost inert gases.
Conventional Corona: Superior to most conventional corona due to electrode configuration and generator frequency.
