The significant property of CPVC, which differs it from PVC is -
-
A.
Improved heat resistance
-
B.
Higher scrap value
-
C.
Heavy weight
-
D.
Decreased heat resistance
Correct Answer:
A. Improved heat resistance
Explanation:
The correct answer is Option A: Improved heat resistance.
CPVC (Chlorinated Polyvinyl Chloride) is created by adding more chlorine to the standard PVC resin. This chemical modification significantly enhances the material's thermal properties. While standard PVC begins to soften at approximately 140 degrees Fahrenheit (60 degrees Celsius), the extra chlorine in CPVC allows it to withstand much higher temperatures, typically up to 200 degrees Fahrenheit (93 degrees Celsius). This makes CPVC suitable for hot water distribution and industrial processes involving high heat, whereas PVC is generally restricted to cold water and drainage systems.
