Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.
