POM plastic pepper ball is used as a sealing ball, and its function is just like the principle of ball valve, mainly through the spherical surface for sealing, but the sealing effect is mainly related to the precision and surface smoothness of POM plastic pepper ball. Generally speaking, the smoother the surface, the better the sealing effect.

POM plastic pepper ball has the characteristics of good precision, high hardness, no water absorption and oil resistance. In addition, when the surface polishing reaches the nanometer level, POM plastic pepper ball has the characteristics of non-adhesion of pollutants, and the sealing effect will always be good. If the surface polishing effect is poor, if the liquid in the pipeline is dirty, the surface of POM plastic pepper ball may be stained with dirt, which will affect the sealing effect of POM plastic pepper ball. Therefore, if the sealing effect of POM plastic pepper ball is good,
