Level IV Bulletproof Vest Nij Ultra-Light Body Armor

I. About the Product

The protective layer structure of the bulletproof and stab-proof clothing is composed of 45 layers of polyethylene fiber non-woven fabric (four layers orthogonal) + 1 layer of 4.5mm thick foam. The bulletproof and stab-proof clothing consists of a top, a bulletproof layer, and a bulletproof layer protective cover. The top is detachable and washable, and the shoulders and waist are adjustable.

• Material: polyethylene fiber
• Size: One Size, Adjustable
• Weight: 2kg
• Bulletproof rating: Level IIIA,III,IV
• Protection area: 0.3 square meters
• Cuff sealing performance: The protective layer is sealed with anti-seepage and anti-seepage black protective cuffs, the edge is sealed evenly, the protective cover material is impermeable, and the hydrostatic pressure resistance is not less than 18kPa
• Wearing flexibility: It is flexible to wear and easy to put on and take off. After wearing, the arms can move freely and the human body's kneeling, jumping, running, pitching, turning over and other movements should not be significantly restricted.

II. Anti-stab parameters

• The stab-proof clothing is vest type, and the shoulder and waist are overlapped with a belt with a silk buckle, which can adjust the size of the shoulder and waist. From the stab-proof surface, the stab-proof layer structure is: 45 layers of high-performance polyethylene fiber stab-proof felt.
• The front and rear stab-proof area is 0.3 square meters, which is easy to put on and take off, flexible and comfortable after wearing.
• The stab-proof layer of the stab-proof clothing is composed of a black, dense, water-tight and light-tight protective cover.
• Use standard test tools and counterweights to test the stab resistance at room temperature to form a 2.4 kg drop. The impact energy of 24J plus or minus 0.5J can effectively sprint into the stab-resistant clothing at 0 degrees, 45 degrees, and no penetration angle.
• The weight of the whole set is less than or equal to 2 kg

IV. Bulletproof parameters

• Ballistic resistance at room temperature: Tested using 1979 7.62mm and 1951 7.62mm. Maximum groove depth should be less than or equal to 25mm for effective hitting, blocking.
• Immersion bulletproof: At room temperature, soak the bulletproof stab-proof suit in water for 30 minutes, and then conduct the bulletproof test. In the case of effective blows, to withstand bullets, the maximum concave depth of the backing should be less than or equal to 25mm.
• High temperature ballistic performance: After high temperature test (+55℃±2℃, constant temperature for 4h), test the ballistic performance within 15min. In the case of an effective hit, the warhead is blocked, and the maximum subsidence depth of the backing is less than or equal to 25min.
• Low temperature ballistic performance: After the low temperature test (-20℃±2℃, constant temperature for 4h), the ballistic performance test is carried out within 15min. In the case of an effective hit, the bullet is blocked, and the maximum sag depth of the backing is ≤25min.
• Bulletproof damp heat performance: After the damp heat test (70℃±2℃, 80% relative humidity, 240h), the bulletproof performance test is carried out. In the case of effective hitting, the bullet is blocked, and the maximum sinking backing depth is less than or equal to 25min.
