Alkest SP 20 is used as a polymerization additive for PVC and polyester, improving control over the process, reducing static electricity and increasing the fluidity of the polymer. Products from the Alkest SP line are lipophilic surfactants, i.e. they exhibit low HLB values. Due to their lipophilic nature, these products are soluble or dispersible in oil, favoring their use in emulsions such as water in oil (W/O). |
