Representative and Technical Collaboration with Expancel - A Company in AKZO NOBEL Group, Sweden, prime producer in the world of Expandable Microspheres.

EXPANCEL® Microspheres are small spherical plastic particles. The Microspheres consist of a polymer shell encapsulating a gas. When heated the gas inside the shell increases its pressure and the thermoplastic shell softens, resulting in a dramatic increase of the volume of the Microspheres.

Microspheres will be mainly available as Unexpanded and Expanded.

Unexpanded Microspheres, EXPANCEL® WU and DU, are used as a blowing agent. When heated the microspheres reach a volume 30 - 50 times greater than before. This phenomenon is used in printing ink for screeen printing and gravure printing to get three dimensional patterns on paper, wallpaper and textiles.

Areas of applications

• underbody coatings and sealantsf for the automotive industry
• paper and board
• coating, spraying and impregnation of woven and nonwoven substrates
• textile printing
• artificial leather
• light weight foam
• silicone rubber
• plastisol

Expanded EXPANCEL® WE and DE Microspheres have a density as low as 30 kg/m3 (114 g/US gallon). This extremely low density in combination with the resilence of the EXPANCEL® Microspheres make them outstanding in comparison with other light weight fillers in weight reduction combined with property imprevement.

Areas of application

• explosive
• polyester putties, body filler, metal body filler
• Paints, crack fillers, thermoinsulating coating, wall and roof coating
