The plastic shell pepper ball itself has a high hardness, but the disadvantage of the plastic shell ball is that it is easy to break under excessive pressure, which also directly affects the application of the plastic shell pepper ball in the high-strength environment. How to make the plastic shell pepper ball not break in the process of use, the best way is to add glass fiber to the POM raw material for modification. After the POM plastic ball is modified with glass fiber, the toughness is significantly enhanced, and the hardness is not changed before the POM plastic ball is modified without glass fiber. Therefore, the POM plastic ball and glass fiber modification can well solve the problem of POM plastic ball fracture.

The raw materials used for POM plastic shell pepper ball and glass fiber can be obtained in two ways. One is to directly buy raw materials that already contain glass fiber. Generally, the content of glass fiber in this raw material is between 10% and 30%. However, because the proportion of glass fiber in POM raw material purchased is fixed, it may not meet the customer's demand for POM plastic ball strength. Another way is to find a factory specialized in POM material modification and reinforcement to help process POM plus glass fiber materials, The advantage of this method is that it can produce a variety of different proportion of POM containing glass fiber raw materials according to the needs of customers, and test the hardness and strength of POM plastic balls by producing POM plastic balls. At present, this is also the best way to strengthen POM plastic balls with glass fiber.

The POM plastic shell pepper ball with glass fiber can solve the problem of poor toughness and cracking, but the surface finish of the plastic shell pepper ball produced after adding glass fiber will be worse. The higher the proportion of glass fiber, the worse the surface finish. Therefore, whether the POM plastic shell pepper ball needs to be modified with glass fiber or not also needs to be selected according to the actual quality requirements of customers.
