Product Introduction
The NIJ Level IV B4C Ceramic Plate is mainly composed of B4C and PE. B4C is a high-performance material with a high melting point, high hardness, and low density, making it an ideal choice for applications in bulletproof materials. Compared with traditional bulletproof materials such as metal plate bulletproof materials, high-performance fiber composite bulletproof materials, and combined bulletproof materials, carbonized boron bulletproof ceramics demonstrate significant advantages. Currently, the NIJ Level IV is the highest level of bulletproof plate, surpassing the performance of Level III bulletproof plates.

The NIJ Level IV B4C Ceramic Plate produced by Winners offers various sizes: 10x12 inches and 10.2x12.8 inches or custom sizes to fit the matching use with bulletproof vests. Our Level IV bulletproof plates can individually block high-speed bullets, and the insert plates are made of durable ceramic materials, with a PE backing on the back to prevent puncturing and stabbing.
The NIJ Level IV B4C Ceramic Plate is divided into SA Standalone and ICW In Conjunction With carrier forms. Standard size: SAPI 250×300 mm; ESAPI enlarged version.
Shooter Cut: Optimal for raising the gun and raising the arm movement; Swimmer Cut: Larger cutting angle.
Curvature: Multi-curve (more than single-curve) for better fit on the chest and back, providing higher comfort during long-term wear.

Main application scenarios and characteristics:
• Tactical field:
Widely used in tactical vests (Plate Carrier) for special forces, law enforcement agencies, and security personnel, especially suitable for high-threat environments where prolonged heavy load combat is required.
• Customization options:
Supports various sizes (such as 250×300mm, 280×360mm) and cutting shapes (SAPI cut, Shooter's cut), and provides single-curved or multi-curved designs to fit the human body.
• Surface treatment:
High-end products often use Polyurea coating, which not only prevents water and wear but also effectively inhibits the splashing of ceramic after breaking, protecting the user from secondary injuries.
