Production Scale Plasma Treatment System - PS350
PS 350
Production Scale Plasma System
The PS 350 Production Plasma System provides complete organic contamination removal without wet chemical problems. Built for the rigor of daily manufacturing use, the PS 350 is designed with durability, performance, and efficiency in mind; using only the highest quality components.
AST Products, Inc. has long had a core business in plasma processing. Cold gas plasma is an energetic process utilizing electrical energy to transform very small amounts of innocuous gases into very chemically reactive and aggressive plasma. The gas plasma interacts with solid surfaces placed in the same environment, causing modification of the molecular structure to create the desired surface properties. Since plasma processing works without using hazardous chemicals, it is environmentally friendly and provides a safe workspace.
Plasma Systems provide highly effective cleaning and surface treatment to almost any material without changing the bulk properties.
Plasma Processing Capabilities
Surface Cleaning: Oxygen plasma treatment is a safe and environmentally friendly alternative to traditional cleaning methods.
Adhesion Promotion: Improving adhesion between two surfaces is a common application. Good adhesion requires strong interfacial forces via chemical compatibility and/or chemical bonding.
Improved Biocompatibility: Biomaterials that come in contact with blood or protein require special surface treatments to enhance biocompatibility.
Enhanced Performance: Surface crosslinking is often used to enhance the performance of polymers.
