What kind of plastic can be armored after it is formed?

• A. Thermoplastic
• B. PVC
• C. Elastomer
• D. Thermoset

Answer: (B)

Armor after forming works best with plastics that can be reheated and reinforced later. PVC is a thermoplastic, so it can be shaped once and then bonded or laminated with an outer armor layer without permanently hardening or changing its basic structure. This reworkability and ability to accept additional protective layers is what makes PVC suitable for armored applications after forming.

Thermosets, once cured, cannot be remolded or easily re-laminated, so they don’t fit the idea of adding armor after forming. Elastomers are flexible and can be reinforced, but their elasticity makes it harder to maintain a rigid armor interface. A general thermoplastic category is accurate, but the specific example that best matches the “armored after forming” scenario is PVC.
