Jinlang microspheres are thermally expandable microcapsules with an average particle size of 5-50μm, which are composed of a thermoplastic shell and a volatile liquid. This expanded microspheres are widely used in TPE materials, high-end shoe materials, wallpaper/floor leather, coatings and paints, cables/art walls, car bottom coatings/sealants, special inks/three-dimensional printing, plasticine toys and other products, can effectively reduce product density, increase resilience, sound insulation, heat insulation and other effects. Compared with conventional chemical foaming agents, the use of expanded microspheres is more environmentally friendly, and can give products a better appearance, better elasticity, and more uniform cells.
