Plasma Treatment of Extruded Profiles

When working with extruded profiles, engineers often experience the problems of adhesion due to the “non-stick” nature of widely used materials, such as PP, PE, TPV and EPDM. Often, achieving good adhesion to these low surface energy materials presents those working with them with quite a headache, as inkjet print and coating adhesion strength is at best poor, but often near impossible.

Plasma Treatment is an excellent option for improving the adhesion quality of “non-stick” polymers, composites and even metals, such as titanium and aluminium. You’ll find our dual-purpose Plasma Treatment solutions on several extrusion lines, improving the adhesion quality of Ink jet, paint, non-slip coatings, flocking and other performance coatings.

How do we do it?

First, let’s talk about Plasma Treatment’s incredible ability to improve the adhesion properties of “non-stick” plastics and composites… When you expose a component to highly active Plasma, a long-lasting change occurs, dramatically improving the adhesion quality that you can achieve, by altering the materials surface energy.

The Plasma Surface Activation process is environmentally friendly, doesn’t alter the bulk property of the material being treated and won’t mark, discolour or damage the extrusion in any way, making it an excellent alternative to abrasion and high temperature flame torch treatment. Following Plasma Treatment, the extrusion will have the required surface energy to ensure good spreading of inks, coatings and adhesives, alongside impressive improvements to the adhesion of paint, flocking and high performance coatings.

We mentioned above that Plasma is a dual-treatment process, but why? Plasma Cleaning is a consistent, repeatable and environmentally friendly method of improving metal cleanliness without the need for environmentally damaging, volatile, solvent based primers and pre-treatment alternatives. Plasma Treatment super cleans the surface of the material undergoing treatment which in turn increases the strength of bond that can be achieved. Plasma is created when a gas (usually compressed air) is subjected to a high-energy discharge: the gas breaks up into electrons, ions, highly reactive free radicals, short wave UV light photons and other excited particles. When these species are excited by a high-energy discharge, they effectively scrub the surface to be cleaned.
