PMMA microspheres manufactured by KBsphere Tech are innovative functional additives presented as free-flowing white powder with perfectly spherical micro morphology.

    When blended into polyolefin resins and cast into films, these functional microspheres form ultra-fine spherical protrusions across the film surface. Such micro-protrusions effectively prevent film-to-film adhesion and deliver outstanding anti-block performance. Unlike inorganic anti-blocking powders, these functional microspheres possess a refractive index closely matched to polyolefin resins. Therefore, films with equivalent anti-blocking performance can achieve superior transparency.

 Key Properties of Films Incorporated with Our Functional Microspheres

1.Significantly lowers film haze to produce ultra-transparent films.

2. Excellent compatibility between organic microspheres and printing inks eliminates white speck defects during post-film printing.

3. Reduces the film’s coefficient of friction substantially, enabling stable high-speed processing such as aluminum vacuum metallization.

4. Strong interfacial bonding between organic microspheres and base films minimizes or eliminates powder shedding issues.
