The shell of pepper ball is basically made of GPPS plastic, but the hardness and toughness of different types of GPPS are different, which has a great impact on the quality of pepper ball. GPPS plastic with too high toughness is not easy to break, and can not play the role of pepper ball breaking and dispersing pepper powder

The GPPS material used for pepper balls can be used with low toughness and moderate impact resistance. The commonly used model is T150 GPPS plastic made in Thailand, which can meet the needs in various properties of pepper balls.
