Cellulose Acetate Spheres are highly spherical plastic particles in sizes between 1mm and 12mm. Custom colors and sizes are available by request. Large, highly-spherical and colorful plastic particles are a useful tool as reference particles in simulation experiments and are successfully used in vision systems and fluidized bed applications.
Other colors, sizes and grades of spherical particles are available:
Spherical Particles (From 1mm to 12mm)
Cellulose Acetate Spheres have high impact and mechanical strength as well as a high dielectric constant and good resistance to a variety of chemicals. Large brightly colored spheres are supplied in dry powder form and are color stable in solution.
Spherical Particles: >98%
