Polymer toner surface tension
WebThe surface tension of a solid polymer cannot be measured directly, as reversible formation of its surface is difficult. Many indirect methods have been proposed, including the liquid … WebThe surface tension of polyethylene extrapolated to 20°C is 34 dynes/cm, consistent with the critical surface tension below which liquids will wet the polymer. The total surface …
