One of the most common applications of cold plasma is the activation of polyolefines, such as polypropylene (PP) prior to an adhesive process.
A cold cold atmospheric pressure plasma is a partially ionized gas. The advantage of a cold atmospheric plasma is that it has room temperature and can be produced on earth at atmospheric pressure. A cold atmospheric plasma produces a reactive mix which very effectively destroys bacteria, fungi, viruses, spores or odour molecules.
The high temperatures which are reached in most plasma applications make many users wonder about process safety, especially when highly sensitive materials are treated. This article addresses open questions concerning temperature and heat conduction during plasma applications and cites critical examples which substantiate the suitability of plasma for temperature-critical processes.
