Plasma technology is often used during the bonding process of two dissimilar materials. Because two materials may have different needs in a bonding agent or glue, a pristine and perfectly clean surface is sometimes mandatory to achieve enough bond strength for the application desired.
This is evident in the medical field as much or more than any other. Products such as catheters and pacemakers require a level of cleanliness only obtainable with plasma or harsh chemical cleaning. Any products designed for use inside the human body cannot be treated with many chemicals. This leaves plasma as the preferred way to clean, modify, and bond materials together.
Bonding plastic to metal is especially challenging because of the differences in the two surfaces. Two dissimilar surfaces often react differently to glues or bonding agents. Glues that work well for an elastic rubber may not work well for aluminum. To bond these two materials together, a clean and bondable surface created by plasma can increase the bond strength significantly.
Depending on the type of plasma used, the plasma not only cleans the surfaces but can also modify the surfaces of plastic and rubber. This is called plasma surface modification. Essentially, the pores of the rubber or plastic are “opened up” and the bonding agent adheres to the material with added strength. This is especially useful on products such as glossy plastics that need to be printed on or glued to a different material.
