Alternative Plasma treatment with atmospheric pressure - PTFE CPI conducts at industrial scale, the surface functionalization of films and fabrics by continuous (roll-to-roll) plasma treatment at atmospheric pressure. CPI has developed specific functionalization and deposition methods based on innovative chemistry. Applications include bonding, digital printing, flexible packaging, lamination, etc. Over a wide range of flexible substrates: Polymer films, fabrics, woven and nonwoven (PP, BOPP, PE, PET, PA, PVC, FEP, PTFE, ETFE, ECTFE, PVDF, PVF, PEEK etc.). Cellulose, paper, ceramics, glass, metal, metallized films.
Alternative Plasma treatment in the low-pressure plasma - PTFE etching Polytetrafluorethylene (PTFE, Teflon) is almost impossible to process by chemicals since it is practically inert against attacks by almost all chemicals, with the only exception of alkaline metal solutions which have an etching effect on PTFE surfaces under formation of alkaline fluorides. A plasma treatment in the low-pressure plasma with hydrogen as a process gas presents an excellent alternative.
Alternative Plasma activation - PTFE Surface activation (or plasma activation) is a method of surface modification with plasma treatment, in order to improve surface adhesion properties of many materials like metals, glass, ceramics, a broad range of polymers and textiles and even natural materials. It is widely used in industrial processes to prepare surfaces for bonding, gluing, varnishing and painting. Plasma treatment achieves this effect through a combination of reduction of metal oxides, ultra-fine surface cleaning from organic contaminants, modification of the surface topography and deposition of functional chemical groups.
Alternative Low Pressure Plasma System - PTFE Low Pressure Plasma Systems are specialized vacuum system components designed, assembled and operated for the specific process of producing plasma chemistry safely and repeatedly. These Low Pressure Plasma Systems offer a wide range of options for surface modification. Some examples of this would be fine-cleaning of contaminated components, plasma activation of plastic parts, etching of organic or inorganic materials, plasma deposition, low friction coating, and coating of plastic parts with PTFE-like layers (polytetrafluoroethylene). Low Pressure Plasma Systems are used in a great variety of industries when it comes to combining materials or changing the surface characteristics of industrial materials.
Alternative Plasma etching - PTFE Plasma Etching is the removal of plastic, silicon, or other non-metallic material using plasma created by exciting ions in a gas, usually oxygen and CF4. The excited ions collide with the material at the atomic level and remove it without the need for chemical etchants. PlasmaEtch work hard to provide superior plasma etching solutions for virtually all applications, and PlasmaEtch are proud to say that they have some of the most effective systems in the industry. Controlling ion density, electron temperature, and the plasma potential are of the utmost importance for ensuring a uniform etching process.
Alternative Plasma etching - PTFE Plasma etching is used to ‘roughen’ a surface, on the microscopic scale. The surface of the component is usually etched with a reactive process gas which gives both a chemical and physical effect on the surface. The chemical etching effect is provided by the reactive gas species in the plasma, which readily react and combine with the surface molecules, removing them into the gas phase where they are pumped away via the vacuum system. The physical effect is caused by high energy ions from the plasma which bombard the surface and physically sputter, or knock, surface atoms off, again removing them to the gas phase. The surface area is greatly increased, increasing the surface energy and making the material easily wettable. Etching is used before printing, gluing and painting and is particularly useful for processing of e.g. POM and PTFE, which cannot otherwise be printed on or bonded.
Alternative Sodium - Ammonia system for PTFE Technetics perform Sodium dissolved in Anhydrous Ammonia etching in Hatfield, PA.
Alternative Ammonia Sodium etch - PTFE Because PTFE has one of the lowest friction coefficients of any solid material on earth, bonding this material needs an equally hi-tech method. G & S Associates uses the most advanced process available, an Ammonia Sodium etch.
