SURFACE TENSION PROPERTIES

The surface tension is very high for a polymer.
According to Wu, the surface tension is 39.3 mN/m, which is divided into a disperse part of 20.5 mN/m and a polar part of 18.8 mN/m.
According to Neumann it is 47.4 mN/m against water.
For Ceramerplus, even higher surface tensions are expected.
