Does Type-2 PVC have a higher tensile strength than Type-1 PVC?

• A. True
• B. False
• C. Type-2 has exactly same tensile strength
• D. Type-1 has lower strength

Answer: (B)

Tensile strength is the maximum stress a material can withstand while being stretched before it breaks. When PVC is categorized into Type-1 and Type-2, the change from Type-1 to Type-2 is typically aimed at properties like flexibility, impact resistance, or chemical stability, not an inherent increase in strength. Because of that, Type-2 is not designed to be stronger in tension than Type-1, so the idea that Type-2 has higher tensile strength is not correct. It may be similar or lower in strength depending on the formulation, but it does not exceed Type-1.
