Scogin® MV is a sodium alginate polymer naturally derived from seaweed. It is typically used as a thickener for aqueous solutions used in industrial applications.
Scogin® MV is a biodegradable sodium alginate–based polymer derived from brown seaweed sourced from sustainably managed farms. As it is naturally derived, Scogin® MV is an excellent replacement for fossil fuel–based additives and polymers used in several industrial applications.
Scogin® alginates, including Scogin® MV, are often used as thickeners, gelling agents, and stabilizing agents in coating, ink, and adhesive formulations. Within the textile industry, for example, Scogin® MV is valued as a thickener in screen printing inks, where it is inert to dyes and fibers and washes off easily. Alginates like Scogin® MV are also ideal raw materials for creating bioplastics.
When added to water at 1 wt%, Scogin® MV produces a solution with a viscosity of 350–500 mPa·s. Solutions of Scogin® MV can also be treated with calcium to form a medium-strength gel with vast temperature stability. Solutions of Scogin® MV are also film forming, offering benefits in applications such as paper sizing and coating. In addition, Scogin® MV exhibits encapsulating functionalities that make it useful in controlled-release applications for liquids, oils, and particles.
