There are not many application scenarios in which pepper balls need to be reinforced. Generally, they need high strength and high pressure. The plastic ball reinforcement technology is mainly to fill a certain proportion of glass fiber into the raw materials of pepper balls, and the strength can be more than doubled.PA pepper balls are generally reinforced by filling 20%-40% of the original PA raw materials with glass fiber. The raw materials used to produce reinforced pepper balls need to be modified and added with glass fiber before they can be produced. When glass fiber is added to the plastic ball raw materials, the hardness of pepper balls is increased, but the surface smoothness is poor. Therefore, the technology of adding glass fiber to pepper balls should choose whether to add fiber and the ratio of fiber according to the actual needs of customers.
