What Does PB Stand For?
PB stands for PolyButylene
PB, or PolyButylene, is a type of plastic widely used in plumbing and piping systems due to its flexibility, resistance to scale and chlorine, and ease of installation. Developed in the 1970s, PB was popular for residential water supply lines; however, its use has declined due to concerns about its long-term reliability and susceptibility to degradation when exposed to certain environmental conditions. Despite this, PB's properties make it useful in various applications beyond plumbing, including electrical insulation and hydraulic systems.
