Shell Composition
Overview
Shell composition describes the ingredients and structural properties of paintball shells, including gelatin content, plasticizers, and manufacturing variables.
Key Points
- Gelatin provides structure and elasticity.
- Plasticizers adjust flexibility and shatter characteristics.
- Shell thickness is not uniform across all paintballs.
- Environmental changes influence shell stiffness.
- Material ratios vary by intended use case.
Details
Paintball shells are formed from gelatin, which provides structural rigidity when dried, combined with plasticizers that control how the shell flexes under stress. The balance of these materials determines breakability and resistance to handling damage.
Shells are not perfectly uniform; variations in thickness occur naturally during the molding process. These differences contribute to slight changes in mass distribution and fracture behavior. Moisture content also affects shell flexibility, as gelatin absorbs or releases water based on storage conditions.
Because gelatin softens in high humidity and hardens in cold temperatures, shell properties are sensitive to environmental conditions. Material composition is therefore optimized for broad performance rather than strict uniformity.
