Product Highlights

AdSperse 868 is an established nucleating agent for the EPS suspension polymerization process. Key characteristics of AdSperse 868 are:

  • High crystallinity due to the high linearity of AdSperse 868: this allows a high content of the blowing agent at the defect site.
  • A narrow molecular weight distribution compared to the majority of waxes used as a nucleating agent in the EPS production process: this provides an improved cell uniformity and homogeneous defect size distribution.
  • Reduced dispersing time due to the product being supplied in a coarse powder form.
