Plasma activation raises surface energies and ensures good wettability, and more complete flow of resins onto almost all low energy polymer materials, including PTFE, silicone rubber and Kapton®. Polymer surfaces are made bondable by the reactive chemistry present in the plasma. New chemical functional groups are formed with strong chemical bonds to the bulk of the plastic allowing both aqueous based solutions and adhesives to wet into every crevice of the material. This allows a tremendous improvement in bonding, sometimes up to 50 times the strength of the traditional bond.
