Latest Patents

Helena holds a patent for "Thermally expandable cellulose-based microspheres having low expansion temperatures." This invention relates to thermally expandable microspheres that consist of a polymeric shell surrounding a hollow core. The hollow core contains a blowing agent, while the polymeric shell is made from carboxylate-functionalised cellulose. The microspheres are designed to start expanding at temperatures ranging from 80° C. to less than 135° C. The process for preparing these microspheres involves mixing the cellulose, an organic solvent, a blowing agent, and optionally, a polymer shell enhancer. The mixture is then sprayed into drying equipment to produce the final product.
