Final answer:
Polycarbonate and acrylic plastic glazing have different strengths and resistances compared to other materials. Polycarbonate is known for its high impact resistance, while acrylic has good weatherability and clarity. However, acrylic is more prone to scratching and cracking.
Step-by-step explanation:
The strength and resistance of polycarbonate and acrylic plastic glazing can be compared to other materials such as double-strength window glass. Polycarbonate is known for its high impact resistance and durability, making it suitable for applications such as riot shields and automotive headlamps. Acrylic, on the other hand, has good weatherability and optical clarity, but it is more prone to scratching and cracking compared to polycarbonate. Both materials have their own advantages and disadvantages depending on the specific application.
