Walxaha cinjirka dabiiciga ah waxaa inta badan laga helaa latex-ka geedka Hevea brasiliensis, oo u dhashay Brazil laakiin hadda inta badan lagu beero wadamada Koonfur-bari Aasiya sida Malaysia iyo Indonesia. Marka qolofta geedka la jaro, latex, oo ah dareere cad oo caano leh, ayaa soo baxa. Latex-kani wuxuu ka kooban yahay qiyaastii hal - biyo saddexaad iyo hal - saddex meelood meel walxo cinjir ah oo ku jira suun colloidal ah. Walxahani waxay ka samaysan yihiin unugyo gaar ah oo latex ah oo loo yaqaan laticifers. Cinjirka ku jira latex-ku waa polymer isoprene ah, oo leh qaacidada kiimikada (C₅H₈)ₙ. Ka dib marka la ururiyo, latex-ku wuxuu maraa habayn si loo go'doomiyo loona sifeeyo walxaha cinjirka.

Dhanka kale, walxaha caagga ah ee la sameeyay waa kuwo aadame - oo laga sameeyay warshado kiimiko ah. Kiimikooyinka batroolka ayaa u adeega sidii walxaha bilowga ah. Tusaale ahaan, neoprene (polychloroprene) waxaa lagu sameeyaa falgalka acetylene iyo hydrochloric acid. Emulsion styrene - caagga butadiene (E - SBR), oo si weyn loogu isticmaalo taayirada baabuurta, waa nooc kale oo macmal ah. Hawshu waxay ku lug leedahay falcelinta polymerization iyadoo la raacayo xaalado gaar ah si loo abuuro polymers leh sifooyin caag ah, kuwaas oo markaa loo farsameeyo qaybo.

Marka laga soo tago ilo caag ah oo bikro ah, caag dib loo warshadeeyay ayaa sidoo kale asal muhiim ah u ah walxaha caagga ah. Qashinka sida taayirada la isticmaalay, calaacalaha caagga ah, iyo alaabada kale ee caagga ah ayaa la ururiyaa. Waa la jajabiyaa, la shiiday, ka dibna waa la farsameeyaa si loo helo walxaha caagga ah.
