DCSBD (Diffuse Coplanar Surface Barrier Discharge) is an atmospheric-pressure plasma technology that generates a thin, uniform layer of low-temperature plasma directly in ambient air, with no vacuum and no noble gases. ROPLASS manufactures DCSBD systems that clean and activate material surfaces within seconds.

No. DCSBD generates homogeneous plasma in ambient air and, where a particular surface chemistry is required, in low-cost gases such as nitrogen or hydrogen. Since no noble gas is consumed, the operating cost of ROPLASS plasma systems remains low.

DCSBD plasma treats polymers (PP, PET, PTFE), nonwoven fabrics, glass, metals, silicon, wood and paper. Published studies further cover printed functional layers such as TiO2, silver nanoparticle inks and graphene oxide. All are flat or web-form materials treated in ambient air.

ROPLASS s.r.o., a Czech manufacturer based near Brno, produces DCSBD atmospheric-pressure plasma systems, from laboratory units to the industrial RPS400 series. All systems are designed and made in the EU.

DCSBD treats moving webs at production speed: polypropylene nonwovens have been processed at up to 450 m/min, with surface activation achieved in under one second. Roll-to-roll ROPLASS units integrate directly into existing converting lines.
