Socal® U1S2

Technical Datasheet | Supplied by Solvay
Socal® U1S2 by solvay is precipitated calcium carbonate. Acts as a nucleating agent, filler, acid scavenger, processing aid and impact modifier. It can also function as a blocking agent for thin film and rheology control agent providing the thixotropic character. It enables high rates of extrusion to be achieved and minimizes fouling of extruder screws and associated plate out. Also improves the melt extensibility which stabilizes the cell structure, improves resistance to white scratch marking. Improves impact resistance in rigid PVC, particularly at low temperatures, by reducing the temperature of transition between the tough and brittle states and can be used to replace or supplement organic impact modifier. It helps to promote smooth finish and high gloss by improving melt elasticity and reinforcement. It minimizes the evolution of acid gas under combustion conditions. It is a highly effective flow aid limiting the compaction of problem powders and also provides control of viscosity without any adverse effect on adhesion. In plastisol wall covering applications, Socal improves the rheology of the plastisol to allow high speed spreading applications to be run. In blown systems, cell structure is seen as more regular. Socal® U1S2 is used in cards (credit, phone), households products/ consumer goods, wiring & cables, pipes, packaging, engineering / manufacturing, buildings & constructions, automotive/ transportation, furniture, footwear and artificial leathers.
