How It Works

Engineered for the Unexpected.

StopForce® is built with proprietary Xtegra fabric at its core, wrapped in fire-rated PVC polyester, and reinforced with a high-performance perimeter rope. Together, they absorb and disperse blast energy. Dangerous forces stay contained.

The Construction

Three layers. One mission.

01

Xtegra Auxetic Core

Proprietary high-tenacity yarn with a negative Poisson's ratio. Under impact, the fabric thickens instead of thinning, capturing fragments before they propagate.

02

Fire-Rated PVC Polyester Shell

An NFPA 701 and CSFM compliant outer envelope shields the core from flame, UV, weather, and chemical exposure in harsh industrial settings.

03

Perimeter Reinforcement Rope

A high-performance rope distributes shock load across the assembly and anchors the curtain securely under blast wave pressure.

The Science

Auxetic yarn that thickens on impact.

Most materials thin out and tear when stretched. Xtegra fabric does the opposite. Its auxetic structure expands laterally as it absorbs energy, packing fibers more densely exactly where the impact lands. The result is a curtain that catches the shockwave and shrapnel ranging 0.1 to 2.3 kg traveling at velocities up to 900 ft/sec.

Xtegra panels are designed to survive multiple deployment cycles and routine pressure tests with a 1 year limited warranty on material and craftsmanship and a 10+ year lifespan, provided documented inspection and correct usage and installation criteria are met.

The Hardware

Built to survive the site.

Every fitting on a StopForce® assembly is selected to outlast the conditions it is installed in. No consumer-grade hardware. No shortcuts.

StopForce stainless trolley and carabiner hardware

316 Stainless Trolleys

Custom rolling hardware glides the curtain into position, then retracts for full equipment access.

Heat-Treated Carabiners

Double-locking, load-rated, field-replaceable. Inspectable and certified for industrial duty.

Welded or Bolted Steel Frame

Custom-engineered to your site geometry. Permanent or modular configurations available.

Reconfigurable Panels

Modular, interlocking sections size to job. Redeploy across sites without reordering custom parts.

Proven in the Field

Tested in real-world scenarios.

Independently validated at Southwest Research Lab. Twelve pounds of C4 detonated 13 feet from the curtain produced a 40 psi blast wave. The 5-gallon bucket and 4 by 4 timber behind the Xtegra panel were untouched.
