1. Ethylene
   Polyethylene
2. Polycarbonite

Polyethylene is used to make many plastics, but only the ultra-high molecular weight polyethylene (UHMW-PE) will produce Dyneema.

   2000
2. 2005

Dyneema was invented several decades ago. It has been in production since 1990.

1. Lighter than air
   Floats on water
2. Fire resistant and self-extinguishing

Although Dyneema can float on water, is fire resistant and self-extinguishing it is not lighter than air. It is lightweight, however, and yet it can still stop a bullet from an AK47.

1. Inert
   Toxic
2. Sustainable

Dyneema is biologically inert so it doesn't cause any negative reactions from the human body when someone touches it.

1. 5 times stronger
   10 times stronger
2. 15 times stronger

Maybe they should rename Superman as the "Man of Dyneema" because this fiber is 15 times stronger than steel!

1. Tight-rope walking ropes
   Pull-start lawnmower cords
2. Fishing nets

Holy mackerel! Dyneema is currently used for high-strength fishing nets.

1. 30 degrees
   60 degrees
2. 90 degrees

Dyneema unidirectional sheets are layered on top of each other at a 90 degree angle in order to disperse the energy of an impact faster and more efficiently.

1. Soft ballistics like handguns
   Hard ballistics like antitank projectiles
2. Both soft and hard ballistics

Although Dyneema can't stop every kind of threat, it can protect against both soft and hard ballistics.

1. Spall liner
   Blast liner
2. Eye liner

Spall are tiny pieces of metal, concrete or other projectiles that can penetrate a vehicle after an explosion. Spall liners are used to catch and absorb these fragments so they don't injure vehicle occupants.

1. Hurricane-resistant houses
   Armored vehicles
2. High school lockers

Dyneema can be shaped and cut easily which makes it an ideal material for armored vehicles that need high-impact protection.

1. 20 to 30 percent less dense
   50 to 75 percent less dense
2. 100 to 125 percent less dense

Dyneema can be 50 to 75 percent less dense than steel armor even when it has a steel or ceramic strike plate on it. That means there's a lot less weight on a person or vehicle!

1. Maneuverability
   Original design
2. All of the above

Dyneema's lightweight characteristic doesn't sacrifice a vehicle's design or maneuverability. Other armored vehicle options are heavier and can impact a vehicles ability to perform, throw off the center of gravity or inhibit their original design.

1. Channels the energy of an explosion back toward where the explosion first occurred.
   Channels the energy of an explosion to the center of the vehicle then up and away from it.
2. Channels the energy of an explosion down into the ground.

The Structural Blast Chimney channels the energy from an explosion to the center of the vehicle and then sends it up and away from the vehicle. This allows the vehicle to stay firmly planted on the ground while protecting the occupants as well.

1. 25 percent
   50 percent
2. 85 percent

85 percent of all aircraft flying in the United States have bullet-resistant cockpit doors made out of Dyneema.

1. 25 percent
   30 percent
2. 35 percent

They found that Dyneema could increase the helmet fragmentation performance by 35 percent.

1. The helmets are half the weight
   The helmets glow in the dark
2. The helmets are invisible to the naked eye

SWAT helmets made with Dyneema are half the weight of previous helmets. This provides officers with added maneuverability and less equipment weight.

1. South Korea
   North Korea
2. Japan

South Korea used Dyneema for some of their Navy patrol boats and hovercraft. Because Dyneema is buoyant it can be made into boat panels.

1. Vancouver
   Beijing
2. London

The Beijing Bureau of Public Safety ordered vests and helmets made of out Dyneema for the 2008 Olympics in their city.

1. High-strength piers
   Mooring and towing lines
2. Ship propellers

Dyneema has been used to make mooring and towing lines in the shipping industry.

1. Surgical cables and orthopedic sutures
   Ambulance tires and gurneys
2. Reinforced hospital walls

The medical field has used Dyneema to create surgical cables and orthopedic sutures.
