[0002] Expandable microsphere foaming agents are a new type of specialty additive with a core-shell structure, where the outer shell is composed of a thermoplastic acrylic polymer and the inner core is composed of spherical plastic particles composed of alkane gases. Upon heating, this foaming agent rapidly expands to several dozen times its original size, achieving a foaming effect. The diameter of expandable microsphere foaming agents typically ranges from 10 to 45 microns. They have a wide range of applications, including reducing production costs, lowering material density, and providing surface modification.
