Brief

StarMicrocel Expandable microspheres are small spherical plastic particles, which are made of a polymeric shell and its wrapped gas. When heated, the internal gas pressure increases and the thermoplastic shell softens, which results in that the volume of microsphere increases surprisingly while the gas still keeps inside the shell.



Microsphere is expandable, so it will result sharp drop in density; the density of microsphere is reduced to 30 kg/m3 from general1000kg/m³

Depending on the applications, microsphere can bring benefits to products in these fields:

- Cost reduced                                                   - Low Density

- Closed chamber                                               - Elasticity

- Compressibility                                                - Internal pressure

- Surface modification                                       - Low thermal conductivity
