Expandable Microspheres Are Thermally Expandable Microcapsules, Consisting Of A Polymer Shell Encaps
March 1, 2023 ⚊ 1 Min read ⚊ Views 50 ⚊ BLOGExpandable microspheres are used in a variety of applications, including as lightweight fillers in composites, thermal insulation, and as additives in coatings, adhesives, and sealants. They are also used in the production of paper and cardboard, where they improve the physical properties of the material and reduce its weight.Expandable microspheres are typically made from materials such as thermoplastic polymers, glass, or ceramics. The shell of the microsphere is made from a material that can withstand high temperatures without melting or degrading, such as phenolic resin or polyvinylidene chloride.
