The plasma treatment process helps in adhesion improvement for secure durable bonding of plastics, silicon rubber and metals. Without plasma treatment many materials like polypropylene (PP), polyether ether ketone (PEEAK) can not be bonded at all or else bonded very poorly. High bonding strength and durable bonding of glass, metal, ceramics and plastics. Plasma treatment improve the adhesion via surface modification simultaniously ultrafine cleaning and bonding strength on the surfaces to be joined.
