Bullets
Plastic is not an effective material for deflecting bullets as it does not provide sufficient resistance or strength to stop a bullet's force. Bullets can easily penetrate through most types of plastic materials. Specialized bulletproof materials like kevlar, aramid fiber, or composite ceramics are used to deflect or stop bullets effectively.

Kevlar is used to stop some bullets. Normally it will stop pistol rounds but other rounds , especially an anti tank round.
