Whether in crisis areas, for special forces or in civilian personal protection, ballistic vests save lives. But what many people don't know is that the effective protection provided by these vests is based on a high-tech material that Schunk has perfected: high-performance technical ceramics.
Ballistic protection does not begin with the vest, but with the ceramic plate that deforms impacts, breaks projectiles, and absorbs their kinetic energy. This is exactly where Schunk comes in: With materials such as SafeGuard GD (RBSiC) or SafeGuard B4C (RBB4C), the company supplies the central protective component of modern hard ballistics systems.
Schunk combines more than 30 years of material expertise with forward-looking manufacturing technology: pressure-cast ceramics for stable series quality and the patented IntrinSiC® 3D printing process, which enables even complex protective structures with low weight.
Military and police organizations in over 20 NATO countries rely on this technology – a testament to the high level of protection achieved by the ceramics used.
Ceramics are what make ballistic vests truly safe – and Schunk provides the backbone of this safety.
Ballistic vests – also known as protective vests – are portable protective systems designed to protect against projectiles, shrapnel, and other threats. They are used worldwide by police, military, special forces, and increasingly in the civilian sector.
A ballistic vest basically consists of two central components:
These ceramic plates are inserted into pockets and are designed to break, fragment, and slow down a projectile upon impact. The remaining energy is absorbed by the soft ballistics underneath.
The protective effect is evaluated internationally according to standards such as NIJ, SK, or STANAG. Only with a hard ballistics component can vests achieve the highest protection classes (e.g., SK4, NIJ IV).
Important: The efficiency of such systems depends heavily on the choice of materials—especially the ceramic used.
The protective effect of ballistic vests stands and falls with hard ballistics. While soft ballistics offer only limited protection, the quality of the ceramic plate determines its ability to stop even high-velocity projectiles.
Ceramics are extremely hard, lightweight, and brittle—ideal properties for taking the edge off projectiles. They fragment the bullet, distribute the energy, and prevent penetration.
Compared to traditional materials such as aluminum oxide or steel, Schunk's high-end ceramics offer superior performance at a lower weight – a decisive advantage for wearing comfort and mobility.
The ceramic is invisible – but without it, no vest is truly safe.
Schunk is a technology leader in ceramic materials for hard ballistics. The company offers: Whether for military protection, police equipment or aviation, Schunk ceramics form the load-bearing protective element in modern systems.
