Dyneema Fiber Rope
. It'll stop a bullet!

Amsteel Blue is made from a synthetic fiber called Dyneema. As well as being used for winch rope for self-recovery winches, it is one of the top-rated fibers used in the manufacture of bulletproof vests. Read on...

Dyneema UD is a unique lightweight composite providing superior anti-ballistic protection, for both personal and vehicle protection.

UD stands for ‘unidirectional’: in Dyneema UD all the fibers are laid parallel, in the same plane, rather than being woven together. Dyneema UD is made of several layers of Dyneema fibers, with the direction of fibers in each layer at 90° to the direction of the fibers in the adjacent layers. The unidirectional configuration of the fibers in Dyneema UD allows the energy transferred from the impact of a bullet or other threat to be distributed along the fibers much faster and more efficiently than in conventional woven fabrics. This is because the absorption power of the yarn in woven fabrics is lost at the crossover points, as these points reflect rather than absorb the shockwaves of the impact. In Dyneema UD, much more of the material is engaged in stopping the bullet, making it more effective against ballistics.

. Dyneema UD is available in two types:

UD-SB - For ‘soft ballistic’ body armor to protect against handgun ammunition:
- Lightweight and flexible for maximum wearing comfort
- Strongly reduced blunt trauma effect
- Excellent protection against more aggressive handgun bullets
- Performance unaffected by moisture.

UD-HB - For ‘hard ballistic’ applications for both personal and vehicle protection:
- Excellent protection against rifle fire (e.g. NATO Ball, AK47, Dragunov)
- Excellent mechanical rigidity and toughness
- Complex shapes can easily be molded
- Resistant to both high and low temperatures, such as in vehicles or in extreme climates
- Performance unaffected by moisture
- Positive buoyancy in water (it floats)
- Ageing-resistant (no effect on performance after 24 months at 90°C)
- Highly resistant to solvents (e.g. oil, gasoline)

"Family Time. Yep, the kids all got jeeps and Mom and Dad were not about to be left in camp cooking. So at the young age of 50, let's make memories on the mountains. Oh, and if the kids see this, It is your turn to cook! Mom and Dad are "Mudding!"
