EXPANCEL 920 DU 40

EXPANCEL 920 DU 40 is a dry powder of unexpanded EXPANCEL microspheres used as a blowing agent in printing ink, weather strips, and similar applications. EXPANCEL 920 DU 40 has a particle size around 40 µm in its expanded form and high solvent resistance, indicating no unfavorable effects are expected when mixed for prolonged periods or at elevated temperatures. This makes EXPANCEL 920 DU 40 well suited for applications in the advanced materials industry where high chemical resistance is required. EXPANCEL 920 DU 40 expands at temperatures between 121-178 °C, making it an ideal choice for processes involving heat treatment without risk of deformation from chemical exposure. Its combination of small, uniform particle size and excellent solvent resistance allows for precise control over physical properties like density and thermal insulation in advanced material formulations.
