Foamed plastic pepper balls are made by plastic foaming technology, but the strength of foamed plastic pepper balls is reduced, which is easy to crack and break. How to increase the strength of foamed plastic pepper balls without affecting the density of plastic pepper balls? The following is a detailed explanation of the technology of strengthening foamed plastic pepper balls.

Foamed plastic pepper balls usually use chemical foaming technology. The principle of chemical foaming is to add chemical foaming agent, which will react chemically at high temperature to generate gas. This part of the climate remains in the plastic ball to form foamed plastic pepper balls. However, the disadvantage of chemical foaming agent is that it will destroy the molecular structure in the plastic during the foaming process, resulting in the reduction of plastic strength. When the proportion of foaming agent is more than 1%, Will significantly reduce the strength of plastic, so the use of chemical foaming agent is the main reason for the strength reduction of foamed plastic pepper balls. In order to solve the strength problem of foamed plastic pepper balls, changing chemical foaming agent into physical foaming agent can solve this problem well. The advantage of physical foaming agent is that the foaming process will not damage the plastic material itself and has limited influence on the strength of foamed plastic pepper balls, so using physical foaming agent is an effective method to solve the strength problem of foamed plastic pepper balls.
