The main purpose of plastic microspheres is to use them in cosmetics and as working abrasives. For example, there are plastic microspheres in toothpaste and facial cleanser, while plastic pepper balls are mainly used as ornaments. The specifications of plastic microspheres are smaller, but the size of plastic pepper balls is required to be more than 1 mm.

The manufacturing method of plastic microspheres is to grind the plastic raw materials through a special plastic microsphere grinder. Although it is called plastic microspheres, it will be found that plastic microspheres are not pure plastic round pepper balls after magnifying with a magnifying glass. It may be more appropriate to call them plastic micro-powders. Because plastic microspheres cannot be degraded, it is forbidden to add plastic microspheres into cosmetics abroad. In order to protect the environment, people have developed degradable plastic microspheres products, and the application market is not wide at present.

The manufacturing method of plastic pepper balls is completely different from that of plastic microspheres. The process used is drawing wires and dicing, and then hot-pressing grinding and synchronous molding.
