Who makes CPVC?

The company’s specialty chemicals division later became part of Lubrizol Advanced Materials, which includes BlazeMaster CPVC and its sister brands FlowGuard Gold and Corzan. Through the 1940s and 1950s, PVC was developed into rigid materials for pipes and other applications.

Which is better copper or CPVC?

Copper’s high melting point is 5-times higher than CPVC’s, so it can withstand much hotter temperatures. Copper won’t burn or support combustion, and won’t carry fire through floors, walls, or ceilings. Copper is also a very versatile material.

What is SDR in CPVC?

Standard dimension ratio (SDR) is a method of rating a pipe’s durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall. Common nominations are SDR11, SDR17 and SDR35. Pipes with a lower SDR can withstand higher pressures.
