Polymer used in bullet proof glass is:A) LexanB) PMMAC) nomexD) Kevlar

The polymer used in bulletproof glass is Lexan.

Here’s a breakdown of why:

Lexan: Lexan is a brand name for a type of polycarbonate resin. Polycarbonate is known for its high impact resistance and optical clarity, making it suitable for use in bulletproof glass. Lexan is commonly used in applications where both safety and clarity are crucial, such as in bulletproof windows and visors.

PMMA (Polymethyl Methacrylate): PMMA, also known as acrylic or plexiglass, is a transparent plastic but is not as impact-resistant as polycarbonate. While PMMA is used in some safety applications, it is not typically used for bulletproof glass.

Nomex: Nomex is a type of aramid fiber used for its heat resistance and flame retardant properties. It is commonly used in fire-resistant clothing and not for bulletproof glass.

Kevlar: Kevlar is another aramid fiber known for its high strength and use in bulletproof vests. However, Kevlar is generally used in the layers of the bulletproof vests themselves rather than in the glass used for ballistic protection.

So, Lexan (polycarbonate) is the correct answer.
