Advantages of polyethylene body armor
One of the main advantages of polyethylene body armor is its lightweight construction. UHMWPE plates can weigh up to 40% less than comparable steel armor while providing similar or enhanced levels of protection. This reduced weight lessens the burden on the wearer, allowing for increased mobility and extended wear times. In addition to being lightweight, polyethylene armor exhibits excellent durability and resistance to environmental factors. Unlike steel, UHMWPE does not rust or corrode when exposed to moisture. It also maintains its protective properties across a wide range of temperatures.NIJ standards for polyethylene armor
The National Institute of Justice (NIJ) sets performance standards for body armor used by law enforcement and military personnel. These standards assess the ballistic resistance and overall quality of armor materials. Polyethylene armor plates are tested against the same NIJ standards as other materials. Common protection levels for UHMWPE include:NIJ Level | Threat Protection |
---|---|
Level III | Rifle rounds up to 7.62x51mm NATO FMJ |
Level IV | Armor piercing rifle rounds like .30-06 M2 AP |
