Polypropylene (PP) particles are small, solid pieces of polypropylene that are used in a wide range of applications, from packaging materials to medical devices and laboratory equipment. These particles can be manufactured to various sizes and shapes, including microspheres, which are uniform in size and spherical in shape. PP particles are known for their durability, chemical resistance, and low density. They are also non-toxic and FDA approved for use in food and medical applications. Therefore, PP particles are commonly used in industries where purity and safety are critical, such as biomedicine and pharmaceuticals. https://www.cd-bioparticle...
