Plastics/rubber. Polymer dispersions and rubber latices (natural and synthetic). Determination of surface tension
| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 20 |
This document specifies two methods for the determination of the surface tension of polymer dispersions and rubber latices (natural and synthetic).
-
Method A is the ring method (Du Noüy ring method).
-
Method B is the plate method (Wilhelmy plate method).
Method A is suitable valid for polymer dispersions and rubber latices with a viscosity less than 200 mPa·s.
Method B is not suitable for polymer dispersions and rubber latices containing cationic surfactants.
Methods A and B are also suitable for prevulcanized latices and compounded material.
In case of dispute, the preferred method is method A (the ring method).
