Expancel SL is a fantastic example of how easily our microspheres disperse in water.

With particle sizes ranging from 10μm – 16μm, Expancel SL expand at temperatures up to 125°C (257°F) and are perfect for getting the right bulk and stiffness in your product or adding antislip properties to your paper coating.

Benefits of Expancel SL

  • Improve bulk, stiffness and flexibility (1% Expancel increases bulk and thickness up to 25%)
  • Reduction in grammage is possible
  • Improve production capacity
  • Adding antislip properties in coatings

Delivered as slurry in 1 m3 containers. Use the product within two years after production date, if unopened.

Not all grades available in all locations. Check local sales office for availability.

SLU means that no salt (NaCL) has been added to the slurry. The addition of salt will further decrease the expansion temperature by approx 8 to 10°C.
