The Many Applications For Techpolymer

Techpolymer is a spherical polymer particle based on hydrophobic monomers such as styrene and methyl methacrylate, a product of Sekisui Kasei’s unique polymerization technology. What does this mean? It means it’s the perfect polymer to serve a wide variety of applications, including light diffusion and adding texture to paints and inks. Techpolymers can be applied to film as an anti-blocking agent. As opposed to some inorganic materials, Techpolymer has superior compatibility for base materials, cutting down on film scratches and degradation.
In cosmetics, Techpolymer’s organic polymer microparticles can be added to skincare products for improved texture and wrinkle coverage. A full range of base makeup and skincare products include primers, foundations, concealers, eyeshadows, lipsticks, moisturizers, and sunscreens. Available varieties of Techpolymer products offer lubricating effects that improve the texture of cosmetic foundations and low compressive strength used for softening effects. Its oil-absorbing properties make Techpolymer ideal matting additives that attach well to the skin, making long-lasting results.
