Question

What thin-film plastic types are most compatible with typical pool water (pH 7.2, normally 5ppm chlorine but up to 15ppm on occasion) in full sun?

Answer 1

Polyvinyl chloride (PVC) and polytetrafluoroethylene (PTFE or Teflon) are the most compatible thin-film plastic types with typical pool water, including water with a pH of 7.2 and chlorine levels up to 15 ppm. They are resistant to chlorine and have good durability and chemical resistance.

Step-by-step explanation:

The most compatible thin-film plastic types with typical pool water include polyvinyl chloride (PVC) and polytetrafluoroethylene (PTFE or Teflon). Both PVC and PTFE are resistant to chlorine and have good resistance to degradation in the presence of pool water with a pH of 7.2 and chlorine levels up to 15 ppm. These plastics are commonly used in pool-related applications due to their durability and chemical resistance.
