Izinhlayiya zerabha zemvelo zitholakala kakhulu ku-latex yesihlahla se-Hevea brasiliensis, esidabuka eBrazil kodwa manje esilinywa kakhulu emazweni aseNingizimu-mpumalanga ye-Asia njengeMalaysia ne-Indonesia. Lapho igxolo lesihlahla liqotshwa, i-latex, uketshezi olumhlophe olufana nobisi, iyaphuma. Le-latex iqukethe cishe ingxenye eyodwa kwezintathu zamanzi kanye nengxenye eyodwa kwezintathu zerabha ku-colloidal suspension. Lezi zinhlayiya zakhiwa ngaphakathi kwamaseli akhethekile akhiqiza i-latex abizwa ngokuthi ama-laticifers. Irabha ku-latex iyi-polymer ye-isoprene, enefomula yamakhemikhali (C₅H₈)ₙ. Ngemva kokuqoqwa, i-latex iyacutshungulwa ukuze ihlukanise futhi icwenge izinhlayiya zerabha.

Ngakolunye uhlangothi, izinhlayiya zerabha zokwenziwa zenziwe ngabantu - ezenziwe ezitshalweni zamakhemikhali. Amakhemikhali e-Petrochemicals asebenza njengezinto zokuqala. Isibonelo, i-neoprene (i-polychloroprene) yenziwa ngokuphendula i-acetylene kanye ne-hydrochloric acid. Irabha ye-Emulsion styrene - i-butadiene (E - SBR), esetshenziswa kabanzi emathayini ezimoto, ingenye inhlobo yokwenziwa. Inqubo ihilela ukusabela kwe-polymerization ngaphansi kwezimo ezithile ukudala ama-polymer anezakhiwo ezifana nerabha, abese ecutshungulwa abe yizinhlayiya.

Ngaphezu kwemithombo yerabha engakasetshenziswa, irabha ephinde yasetshenziswa nayo ingumsuka obalulekile wezinhlayiya zerabha. Izinto ezilahliwe ezifana namathayi asetshenzisiwe, amathe erabha, neminye imikhiqizo yerabha ziyaqoqwa. Ziyasikwa, zigaywe, bese zicutshungulwa ukuze kutholakale izinhlayiya zerabha.
