Ekirungo ekiziyiza okukaddiwa kwa kapiira kye kirungo ekikulu eky’ebirungo ebigattibwa mu kapiira, ttani nga 600,000 mu kiseera kino, ebitundu nga 40% ku muwendo gwonna ogw’ebirungo ebigattibwamu ebya kapiira.
Ebirungo ebiziyiza okukaddiwa kwa kapiira bisobola okwawulwamu: p-phenylenediamine, quinoline, diphenylamine, naphthalene amine, phenol ne phosphite ester.
Mu bino, ekibinja kya P-phenylenediamine kikola ebitundu 56%, ekibinja kya quinoline kikola ebitundu 20%, ate ebirala ebiziyiza okukaddiwa nga phenols, diphenylamines, phosphite esters biri wansi wa 10%.
Olw’enkulaakulana ey’amangu ey’amakolero g’ebirungo ebigattibwamu mu Asia naddala mu China, okukola ebirungo ebigattibwa mu kapiira mu nsi n’ebitundu eby’amawanga g’obugwanjuba ebikulaakulanye kigenda kikendeera mpolampola.
Ebitongole ebikulu ebikola ebintu eby’ebweru bikyagenda mu maaso n’okugatta n’okuddamu okutegeka, okwongera ku kuddamu okutegeka amakolero, okutumbula okuvuganya kw’ebitongole, n’okunoonya emikisa emipya n’ekifo eky’enkulaakulana.
Mu kiseera kino, bino wammanga ebikulu eby'okulwanyisa okukaddiwa Agent Production Enterprises.
1.Flexsys .
Kkampuni eno ekwatagana ne Eastman Chemical, Amerika, kye kintu eky’enjawulo eky’ensi yonna eky’ekika ekisinga okujjuvu, ekipimo ekisinga obunene eky’abakola eby’okwongera mu kapiira.
Mu kiseera kino, zikuuma ebirungo bya P - phenylenediamine ebiziyiza okukaddiwa byokka, ekibiriiti ekitasaanuuka n’ebintu ebirala ebitonotono eby’okugattako ebya kapiira.
Ekintu kya Fulex ekikulembeddemu ye sulfur etasaanuuka, ng’obusobozi bwonna obw’okufulumya 200,000 ttani/omwaka ate ekifo eky’obwannannyini mu katale ak’omulembe.
2.Eddagala ly'ekika kya lanxess .
LANXess Chemical Co., Ltd. ye bitongole ebikulu eby'okufulumya ebigimusa ebijjuvu eby'ebweru eby'ebweru .
Mu katale k’e Bulaaya, ebintu byayo eby’okusannyalala ebya kapiira n’ebintu bya China eby’okusannyalala bivuganya;mu Bulaaya ne North America, ekirungo kyabwe ekiziyiza okukaddiwa kwa kapiira TMQ kivuganya ne Nanhua ne COMAC.
3.Chemtura .
Esooka ye kkampuni ya Amerika eya Compton, ebadde egula kkampuni ya UNIROY ekola ebigimusa bya kapiira ne kkampuni ya Amerika eya Great Lakes (eyali emu ku kkampuni ezisinga obunene mu nsi yonna ezikola obuveera), eyakyusibwa erinnya mu 2005 Koju Ya.
Oluvannyuma, kkampuni yaggalawo mpolampola ekirungo kya kapiira naddala ebyuma ebikola ekirungo ekikaddiye, okutuuka ku polyurethane elastomer, amafuta agasiiga, ekirungo ekikola ku ttaka, okukola obuveera.
Mu kiseera kino, zikuuma obuuma obumu obutono obuyitibwa ttani mu Taiwan ne North America, okusinga nga bukola ebirungo ebiziyiza okukaddiwa kw’obutale obw’enjawulo.
Okugatta ku ekyo, ebitongole ebimu eby’okukola kwayo okwa OEM eby’abamu ku baziyiza okukaddiwa n’abatumbuzi.
4.Agrofert .
Eno ye kampuni enkulu esoose mu Czech Republic, nga bizinensi yaayo erimu ebyobulimi, amakolero g’eddagala, emmere n’ebirala.Obusobozi bw’okukola ebigimusa bya rubber nga 30, 000 ttani/omwaka.
Kkampuni eno ye kampuni enkulu ekola ebigimusa bya kapiira mu buvanjuba bwa Bulaaya.
5.Eddagala ly'eggwanga ery'obutonde (Nocil) .
Nocil esangibwa mu kemiko amakolero 40km okuva e Mumbai.
Nocil ye Buyindi esinga okukola eddagala lya kapiira. Ekola ebyuma ebikuba ebipiira n’ebiziyiza okukaddiwa, ng’erina obusobozi bw’okufulumya ttani ezisukka mu 10,000 ku bika bingi.
Buyindi era erina ebitongole ebiwerako ebikola ebigimusa bya kapiira, naye obusobozi buli wansi wa ttani 10, 000 .
Kkampuni zino ez’Abayindi zigenda kujja e China okugula P-aminodiphenylamine era zikole 6PPD.
6.KKPC .
Okuva mu 2008, obusobozi bw’okufulumya 6PPD ya Jinghu Petrochemical bwongerwako mangu, nga minzaani egenda mu maaso n’okugaziwa okuva ku 20,000 ttani/omwaka okutuuka ku 50,000 ttani/omwaka mu 2011.
Ekirungo kyakyo eky’omu makkati, P - aminodiphenylamine, kisinga kuweebwa Jiangsu Shengao Chemical Co., Ltd.
Ku nkomerero ya 2012, kkampuni eno yagaziya ekifo kyayo ekikola MIBK.
Mu kiseera kino, Jinghu Petrochemical efuuse pulodyusa wa MIBK asoose mu Asia ate owookubiri mu nsi yonna.
