Which material is described as hard wearing and durable?

• A. PVC.
• B. MF.
• C. LDPE.
• D. HDPE.

Answer: (A)

Hard wearing and durability come from a material that resists abrasion, holds up under repeated use, and withstands environmental factors. Rigid PVC fits this description well: its stiff polymer structure gives good surface hardness and abrasion resistance, so it resists wear over time. It also offers chemical resistance and, with stabilizers, good weathering resistance, helping items last longer in outdoor or damp conditions. That combination makes PVC a common choice for durable, low-maintenance parts like window frames and pipes. By comparison, LDPE is flexible and prone to wear more quickly, while HDPE is tougher but still not as rigid as PVC in typical wear scenarios. Melamine formaldehyde is very hard and heat resistant but can be brittle, which limits its suitability for general wear-heavy use.
