1) Kuramo HCL no kuyigabanya, bikabuza ingaruka zayo zo kwihutisha. Ubu bwoko bw'ibitera imbaraga burimo umunyu wa lead, isabune ya aside organic metal, compounds za organotin, compounds za epoxy, umunyu udakomoka ku bimera, n'umunyu wa thiol metal. Bishobora gukorana na HCL no kubuza PVC gukorana na HCL.
2) Gusimbuza atome za chlorine zidahindagurika mu tunyangingo twa PVC bibuza HCL gukuraho. Iyo organic tin stabilizer ihuye na atome za chlorine zidahindagurika za molecule za PVC, organic tin izasimbuzwa atome za chlorine zidahindagurika mu mubiri uhuza.
3) Uburyo bwo kongeramo ibintu hamwe n’imiterere ya polyene bubangamira ishyirwaho ry’uburyo bunini bufatanye kandi bugagabanya ibara. Umunyu wa aside unsaturated cyangwa esters zirimo imigozi ibiri, inyura mu buryo bwa diene addition hamwe na molekile za PVC binyuze mu guhuza imigozi ibiri, bityo bigahungabanya imiterere yazo ifatanye kandi bikabuza ihinduka ry’amabara.
4) Gufata radicals zidafite imbaraga no gukumira ingaruka za oxidation, iyi stabilizer y'ubushyuhe ishobora kugira ingaruka imwe cyangwa nyinshi.
Igikoresho cyiza cyo kubungabunga ubushyuhe cya PVC kigomba kuba ikintu gifite imikorere myinshi cyangwa uruvange rw'ibikoresho bishobora kugera ku nshingano zikurikira: icya mbere, gusimbuza ibintu bikora n'ibidakora neza; Icya kabiri ni ukwinjiza no kugabanya HCL isohoka mu gihe cyo gutunganya PVC, gukuraho ingaruka za HCL zo kwangirika mu buryo bwikora; Icya gatatu ni ugukuraho cyangwa gufunga iyoni z'icyuma n'indi myanda yangiza igira uruhare mu kwangirika; Icya kane, ubwoko butandukanye bw'ibinyabutabire bushobora kubuza gukomeza gukura kw'imigozi idahagije no kubuza ibara ryangirika; Icya gatanu, bigira ingaruka zo kurinda no kurinda urumuri rwa ultraviolet. Ubusanzwe, ibipimo bibungabunga ubushyuhe bikoreshwa hamwe hashingiwe ku buryo bwihariye bwo gukora, kandi ikoreshwa ryabyo ku giti cyabyo ni gake cyane. Byongeye kandi, ubwoko bwinshi buri mu ishusho y'ifu, bumwe bukaba ari imiti ihumanya cyane. Kugira ngo byorohere gukoreshwa, birinde uburozi bw'umukungugu, kugabanya ibintu bihumanya cyangwa kubisimbuza ibintu bidafite uburozi, ubwoko bwinshi bw'ibipimo bihuza byakozwe mu gihugu no mu mahanga mu myaka ya vuba aha. Urugero, uruhererekane rw'ibice bihuza ibidukikije bya German Bear, kimwe n'ibice bihuza ibidukikije bya organic tin cyangwa organic tin stabilizers bituruka mu bihugu nka Leta Zunze Ubumwe za Amerika, Ubudage, Ubuyapani, n'Ubuholandi, byose bifite isoko rinini mu Bushinwa. Kubwibyo, ni ngombwa byihutirwa ko iterambere ry'inganda za pulasitiki mu Bushinwa riteza imbere byimazeyo ikoreshwa ry'ibice bihuza ibidukikije bishya bifite ubushobozi, bihendutse, bidafite ivumbi, bidafite uburozi cyangwa uburozi buke.
