The most common type of gasket utilized in North America is a metal-reinforced elastomer, commonly referred to as a Rieber sealing system. [39]
This increase in elemental chlorine content contributes to CPVC's increased expression of chlorine-based characteristics, such as chemical durability, resistance to acids, bases, and salts; susceptibility to ammonia-based compounds, aromatics, esters, ketones; [9] chemical stability; heat energy transfer resistance. CPVC is commonly used in ...
