Hollow Shells

Highly Engineered Hollow Shells

Trelleborg’s highly engineered hollow shells, reduce weight in composite or syntactic materials, without compromise. With our unique engineering ability, we pick up where traditional glass microspheres filler stops.Our proprietary processing techniques allow the fabrication of hollow shells made of unconventional materials such as ceramic and metal. Our custom and stock hollow shells will increase your design space and allow you to achieve mission critical performance where it counts. Let us help you make your product or material lighter, stronger, more shock absorbent and fire proof.
