Fragment Trap

The Fragment Trap uses a super absorbent → hydrogel system: sealed powder packs react with water to form a gel that captures fragments from an explosive event. The L‑shaped module deploys quickly around a suspect item, is reusable if not damaged, and the gel can be returned to liquid with a dedicated chemical — both gel and chemical are harmless to the environment. Custom forms and sizes are available for different end uses.

Why teams choose Fragment Trap

• Fast to deploy: partial protection ~2 min after filling; ~15 min to full gel strength (at ~10 °C water). Reaction accelerates with warmer water.
• Reusable design: if not damaged, gel can be liquefied in ~15 min and the unit reset.
• Environmentally considerate: gel and liquefied solution are harmless and can be flushed to sewer.
• Flexible setup: L‑shape enables various placements around an item; custom shapes/sizes available.

What’s in the unit

• Fragment Trap module with sealed super absorbent powder packages (water‑activated).
• 2″ quick‑release coupling for water fill (user‑supplied water).

Key specifications

• Weight (empty): 35 kg. Height (filled): 1000 mm. Width: 1400 mm. Thickness: 400 mm nominal.
• Filling time: ~2 min (partial protection). Gelling time: ~15 min to full protection at ~10 °C water. Liquefaction time: ~15 min.
• Allowed water temperature: 0–60 °C (warmer = faster reaction).
• Hydrogel: polymer powder + water. Filling pressure: 5 bar. Fitting: 2″ quick‑release coupling.

Tested performance:

• Shot bomb test (TM 2469): ~3300 lead/steel shots around 500 g explosive; protective wall provided good protection — indicator sheets not perforated (explosive 0.5 m from shield, 0.3 m above ground).
• 81 mm mortar shell test (TM 2469): explosive 0.1 m from shield and ground; good protection — indicator sheets not perforated.
• Ballistic test (TM 2367): gel‑filled protective wall (PVC‑coated fabric) to STANAG 2920 with 1.1 g FSP — V50 = 691 m/s (wall nominal 200 mm, ~320 mm after filling). Figures are for the gel‑filled protective wall configuration reported; consult manufacturer for applicability to specific Fragment Trap builds.

Frequently asked questions

How does it work?
Super absorbent powder reacts with water to form a hydrogel that absorbs and traps fragments from an explosion.

How quickly is it usable?
Expect partial protection in ~2 minutes after filling, with full protection in ~15 minutes at ~10 °C water. Warmer water reduces gel time.

Is it reusable?
Yes, if the unit isn’t damaged, the gel can be returned to liquid in ~15 minutes using the specified chemical and the unit reset.

Is it safe for the environment?
Both the hydrogel and the liquefied solution are harmless and can be flushed to sewer.

What are the physical dimensions?
Approx. 1000 mm (H) × 1400 mm (W) with 400 mm nominal thickness; 35 kg empty.

What water supply does it need?
Fill via 2″ quick‑release coupling at around 5 bar; water temperatures 0–60 °C are allowed.
