What are the differences between PVC, UPVC, PPR, and PE? Could some expert explain this?

PVC: It has good tensile and compressive strength, excellent corrosion resistance; however, it is less flexible than other plastic pipes and becomes more brittle at low temperatures. CPVC: It boasts excellent heat resistance, with a heat distortion temperature of 100 degrees, and good chemical resistance. PE: Light in weight, highly flexible, with high impact resistance and good low-temperature performance; however, it has low compressive and tensile strength. PPR: It has good toughness, high strength, excellent processability, good creep resistance at high temperatures, and good transparency.
