The performance of polyether modified polysiloxane

According to the corresponding national standard methods, the surface tension, HLB value, CMC value and emulsification performance of the product were determined. Compare the hydrolytic stability with other three kinds of organic silicon surfactants, the experiment result shows that the hydrolytic stability of product is better than the similar products. The key to reduce the hydrolysis rate of polyether modified polysiloxane surfactant is to reduce the contact of polysiloxane chain in surfactant molecules with water solution. For methoxy-terminated polyether modified polysiloxane, the methyl ether open as the umbrella, which can reduce the contact of polysiloxane chain in surfactant molecules and water solution to a certain extent, so the hydrolysis stability raise.
