Option 1, Polyvinyl chloride (PVC), is not used for bulletproof material; it is typically used for manufacturing pipes, cables, profiles, and flooring.
Option 2, Polyamides often referred to as Nylon, is used primarily in the textile industry, automotive applications, and other areas where high wear resistance and flexibility are required. Still, it`s not specifically used for bulletproofing.
Option 3, Polyethylene, a lightweight thermoplastic, is used more for containers, toys, or in the chemical industry, not particularly suitable for bulletproof materials.
Option 4, Polycarbonates, are indeed used frequently in bulletproof material. This is due to their high impact resistance, strength, and transparency. Polycarbonate materials are used in bulletproof windows, eyewear, and other applications where high impact resistance is required. So, the correct answer is option 4.
