HDPE Plate Level III (3) is in conjunction with Body Armor level III-A is a ceramic trauma plate that the United States Armed Forces are currently using. Therefore, the Kevlar Interceptor vest itself stop projectiles up to and including 9×19mm Parabellum submachine gun rounds. In addition to fragmentation, to protect against higher-velocity rifle rounds, HDPE Plate Level III (3) is necessary. This order comes with two plates.
One Plate: $ 283.99 + Free Shipping
Two plates: $516.99 Plus Free Shipping
- Ballistic material: HDPE (Polyethylene thermoplastic made from petroleum).
- The protection level is III according to NIJ interim requirements.
Bulletproof vests are trapping and slow bullets down as they attempt to pass through the vest. Therefore, the Bulletproof Vests come in two different types; hard and soft. In addition, the ‘soft’ armors protect against most handgun and small arms ammunition, whereas ‘hard’ armors are stopping high caliber and armor-piercing rounds.
- Size: 300×250 mm ± 5. = 10X12 inch
- Thickness: 20mm ± 2. = 1 inch
- Weight: ±1450 gr. = 3 pounds and 3.15 ounces
HDPE is known for its large strength-to-density ratio. Therefore, the density of HDPE can range from 0.93 to 0.97 g/cm3 or 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching. Therefore, giving it stronger intermolecular forces and tensile strength than LDPE. For instance, the difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C/ 248 °F for short periods). in conclusion, High-density polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions.
