Electrical Air Plasma Treatment in India

Electrical Air Plasma Treatment for Indian Manufacturers

Electrical “air plasma” is a corona discharge spot pretreatment process used by plastics manufacturers in India and worldwide (also termed blown air plasma/forced air corona/blown arc). This treatment head consists of two hook electrodes in close proximity to each other connected to a high-voltage transformer generating an electric arc of approximately 7 to 12kV, and lower frequency 50 to 60 cycles/sec (relative to electrical corona discharge). Then using forced air, a continuous electric arc produces a corona discharge, “plasma.” No positive ground is needed. This pretreatment process has virtually no cleaning capabilities. Ozone is produced.

Myth: Corona discharge spot treatment yields longer shelf life than flaming.

Fact: Scholarly studies show flame plasma on polyolefins produces longer post-treatment shelf life due to its relatively shallower depth of treatment.
