Openair® Plasma makes it a reality: long-term adhesion with new warm melt adhesives
Openair® Plasma process makes it possible for the first time to
achieve reliable results when using newly developed one-component
warm-melt polyurethane (PUR) adhesives on non-polar plastics, such as
Pretreatment with Openair® Plasma generates the required high
surface tension on the materials to be bonded.
technique for combining Openair® Plasma with warm melt adhesives was
successfully developed in collaboration with adhesives manufacturer
The advantages of warm melt adhesives:
- High green strength
- Fast inline leakage testing
- Increases productivity (>15%)
Hella Australia Pty Ltd.
In 1995, Openair® plasma technology was used for the first time in standard production of automobile headlamp housings in Germany. Today, it has become an established part of applications around the world. At HELLA, Australia, the high process safety of the plasma process is especially valued.
