Suitable Materials & Processes
Crerax expandable microspheres are designed for use with thermoplastics (PVC, PP, PE…), thermosets (polyurethane, epoxy, phenolic, unsaturated polyester resins…), thermoplastic elastomers (TPR, TPV, TPU…), rubber (EPDM, silicone, NBR, BR…), coatings, paper, and adhesives. They are compatible with processing methods such as injection molding, extrusion, blow molding, and calendering, requiring no significant changes to existing equipment or processes. Even low loadings deliver exceptional performance. For example, adding just 1% microspheres in extrusion can reduce density by 10–30%.
