It's the mundane stuff of plastic bags and sandwich boxes, but polyethylene has a more streetwise talent: in the form of dense, high-molecular-weight fibres it can stop a bullet in its tracks.Jun 2, 2007
What are polyethylene plates?
Polyethylene (PE) plates are made from ultra high molecular weight polyethylene (UHMWPE), which is a ballistically resistant plastic. PE plates are made of many layers of the PE material that have been compressed and heated until it forms a hard monolithic plate.Feb 4, 2021
Why is polyethylene used in body armor?
HIGH-DENSITY POLYETHYLENE This is important because it makes all those molecules pack in real close together, making the material stronger. When we say stronger, we mean in the ballistics world stronger in tensile strength.
Are ShotStop plates good?
Here's the thing: it works! Head over to social media to see videos of trials people have conducted against the body armor. The typical findings are that ShotStop characteristically stops well above its NIJ rating. I've even seen videos of people blowing up the plates then shooting them to try to penetrate.
Are ShotStop plates NIJ certified?
Are all of your products compliant to NIJ standards? All of our body armor plates have been tested to meet or exceed NIJ requirements for their respective levels. All but one of our products the Duritium III+GT “special threat” plate are NIJ compliant.
What is the strongest body armor made of?
Kevlar
Does ceramic make good armor?
Ceramic is better at absorbing and dispersing energy than steel. This will result in less broken ribs, broken sternum, and collapsed lungs. Ceramic does better against supersonic armor-piercing bullets than steel. This customization gives ceramic plates better protection.Sep 9, 2020
Is polyethylene body armor any good?
Polyethylene Armor It's known to have excellent chemical inertness, self-lubricity, and impact resistance. It's also proven to be 15 times more abrasion-resistant than carbon steel.Sep 9, 2020
What is polyethylene armor?
Polyethylene armor is manufactured by bonding unidirectional UHMWPE (Ultra High Molecular Weight Polyethylene) fibers over an HDPE (High-Density Polyethylene) sheet. The sheets are cut to shape, placed in a mold, and compressed under high heat and pressure resulting in a cohesive hard armor plate.
What kind of steel is armor plate?
What type of steel is used in body armor? ANSWER: AR500 is a very common steel plate that is used in body armor. It is a specific kind of abrasion resistant steel with a high surface hardness, also called Brinell Hardness, of 477-534.
What plate materials are used in hard armor?
The most popular form of hard armor plates are made from ceramics or ceramic composites, often with a para-aramid backing such as Kevlar®®. These are generally the cheapest forms of hard armor, but are also the heaviest.
