The Types segment classifies non‑metallic shot peening abrasives by material composition and particle morphology, encompassing ceramic beads (e.g., alumina, silicon carbide), glass beads (soda‑lime, borosilicate), polymer beads (nylon, polyurethane), and composite beads (ceramic‑coated polymer). Ceramic beads, characterized by high hardness and low deformation, dominate high‑stress applications such as aerospace and energy, contributing disproportionately to premium‑price revenue despite a smaller volume share. Glass beads, offering moderate hardness and excellent sphericity, are preferred in automotive and general industrial contexts where surface smoothness and lower residual stress are critical, thus representing the largest volume share. Polymer beads, with their low density and elastic impact, serve niche applications requiring minimal surface distortion, adding modest but growing value as lightweight designs proliferate. Composite beads combine the impact energy of ceramics with the cushioning effect of polymers, positioning them as an emerging hybrid solution that is expected to capture incremental market share as manufacturers seek balanced performance.
