Mbere yo gushyira mu bisobanuro, reka tubanze dusuzume icyo buri gikoresho gikozwemo. PPR ni incamake ya polypropylene random copolymer, mu gihe CPVC ari chlorine polyvinyl chloride ikorwa binyuze mu nzira ya chlorine muri polyvinyl chloride.
PPR ni bwo buryo bwo gukwirakwiza imiyoboro bukoreshwa cyane mu Burayi, mu Burusiya, muri Amerika y'Epfo, muri Afurika, muri Aziya y'Epfo, mu Bushinwa no mu Burasirazuba bwo Hagati, mu giheCPVCikoreshwa cyane cyane mu Buhinde na Megizike. PPR ni nziza kurusha CPVC atari ukubera ko yemerwa na benshi, kandi ni nziza ku mazi yo kunywa.
Noneho, reka tugufashe gufata icyemezo kitekanye, usobanukirwe impamvu imiyoboro ya CPVC idateje akaga n'impamvu wagakwiye guhitamoImiyoboro ya PPR.

Plasitiki yo mu rwego rw'ibiribwa:
Imiyoboro ya PPR ntabwo irimo ibintu bikomoka kuri chlorine kandi ni myiza ku mubiri w'umuntu, mu gihe imiterere y'imiyoboro ya CPVC irimo chlorine, ishobora gutandukanywa no gushonga mu mazi mu buryo bwa vinyl chloride hanyuma ikirundanya mu mubiri w'umuntu.
Hari ubwo hagaragaye ko imiyoboro ya CPVC idafite ubushobozi bwo gufata neza kandi ikenera imiti ihumanya ikirere, mu gihe imiyoboro ya PPR ihuzwa n'ubushyuhe buvanze kandi ikabuza imiyoboro minini no gufata neza cyane. Imbaraga zihuriweho zituma habaho ubwoko ubwo aribwo bwose bwo gusohoka. Leta Zunze Ubumwe za Amerika zakoze ubushakashatsi bwinshi ku bijyanye no gusohoka kw'ibintu biteje akaga nka chloroform, tetrahydrofuran na acetate mu mazi yo kunywa binyuze muImiyoboro ya CPVC.

Imiti isukura ikoreshwa muri CPVC ishyira ubuzima bwawe mu kaga:

Komisiyo ishinzwe ubucuruzi bw'imiyoboro ya California ishinzwe gusuzuma ingaruka z'imiyoboro ku buzima, ikaba ari ikigo gishinzwe gutanga ibyangombwa ku bapfumu muri California, muri Amerika. Yahoraga ishyigikira cyane ingaruka mbi z'imiyoboro ikoreshwa mu guhuza imiyoboro ya CPVC. Byagaragaye ko iyo miyoboro irimo ibintu bitera kanseri mu nyamaswa kandi ifatwa nk'aho ishobora kwangiza abantu. Ku rundi ruhande, imiyoboro ya PPR ntabwo isaba imiyoboro iyo ari yo yose kandi ihuzwa n'ikoranabuhanga rishyushye, bityo ntigira imiti y'uburozi irimo.

Umuyoboro wa PPR ni igisubizo cyiza:
Imiyoboro ya KPT PPR ikozwe mu bikoresho fatizo byiza cyane, ifite ibiribwa byiza, yoroshye kuyikoresha, ikomeye, kandi ishobora kwihanganira ubushyuhe buri hagati ya -10°C na 95°C. Imiyoboro ya KPT PPR imara igihe kirekire cyane, ishobora gukoreshwa mu gihe kirenga imyaka 50.
