Before entering the specification, let us first figure out what each material is made of. PPR is the abbreviation of polypropylene random copolymer, while CPVC is chlorinated polyvinyl chloride which is produced through the process of chlorination to polyvinyl chloride.
PPR is the most widely used piping system in Europe, Russia, South America, Africa, South Asia, China and the Middle East, while CPVC is mainly used in India and Mexico. PPR is better than CPVC not because of its wide acceptance, and it is safe for drinking water.
Now, let us help you make a safer decision, understand why CPVC piping is unsafe and why you should prefer PPR piping.

Food grade plastic:
PPR pipes do not contain chlorine derivatives and are safe for the human body, while the CPVC pipe structure contains chlorine, which can be separated and dissolved in water in the form of vinyl chloride and accumulate in the human body.
In some cases, leaching has been found in the case of CPVC pipes because they have weak adhesion and require chemical solvents, while PPR pipes are joined together by heat fusion and prevent the thicker pipes and stronger adhesion. The combined forces lead to any type of leakage. The United States has conducted many studies on the leaching of hazardous substances such as chloroform, tetrahydrofuran and acetate into drinking water through CPVC pipelines.

The solvents used in CPVC put your health at risk:

The California Pipeline Trade Commission is responsible for reviewing the health effects of piping systems and is the plumber certification agency in California, USA. It has always highly advocated the hazardous effects of solvents used to connect CPVC pipes. It has been found that the solvent contains carcinogenic elements in animals and is considered to be potentially harmful to humans. On the other hand, PPR pipes do not require any solvents and are connected by hot-melt technology, so they do not contain toxic chemicals.

The PPR pipeline is the healthy answer:
KPT PPR pipes are made of high-quality raw materials, food-grade, flexible, strong, and can withstand a temperature range of -10°C to 95°C. KPT PPR pipes have a very long service life, which can be used for more than 50 years.
