一．Product Property
Its characteristics include excellent surface activity, which can significantly reduce the surface tension of the solution. It is suitable for applications such as wetting, dispersion and emulsification. Moreover, some models have low foam or defoaming properties, making them suitable for industrial cleaning and process additives.
