Techpolymer is a spherical polymer particle created by Sekisui's polymerization technology.

Techpolymer, based on hydrophobic monomers such as styrene and methyl methacrylate, can provide various functions in a wide variety of applications through cross-linking, pore formation, functionalization, improvement of heat- or solvent-resistance, or adjustment of refractive index.

Major applications include light diffusion, cosmetics, paint and ink, and film.
