We are a world leader in alginate technology. Alginates are naturally occurring, biodegradable polysaccharides extracted from brown seaweed. They are water soluble and have the unique ability to thicken as well as form gels in the presence of calcium ions.
Scogin® and Protaweld® are our high-functioning alginate products. The diversity of our seaweed allows us to manufacture a wide variety of Scogin® and Protaweld® products with various viscosities and gel strengths. Scogin® and Protaweld® are suitable for a range of industrial applications.
- Cold / hot water solubility
- Viscosity and gelation
- Naturally occurring biopolymer: safe, renewable and consumer-friendly
- Rheology modification
- Suspension agent
- Film-forming
- Powerful at low concentrations
