Our product is the so-called “Thermoexpanable Microcapsules” known by the trade name “MATSUMOTO MICROSPHERE”.
“MATSUMOTO MICROSPHERE” is composed of two components; a core and a shell.
The core is low molecular hydrocarbon while the shell is made of thermoplastic polymer.
When the product is heated, the shell material is softened and the low molecular hydrocarbon is vaporized to cause internal pressure increase, leading to shell expansion.
Our product is used for primarily reducing weight, bulking and adding functionality in various applications and for various purposes. Typical applications are resin molding, sealants and adhesives, coatings, automotive parts and underbody coating, heat and acoustic insulating materials, and beyond.
