Caag Ethylene propylene (inta badan binary ethylene propylene caag) ayaa loo isticmaalaa tiro aad u badan sida beddelka index viscosity (OVI ama VII) ee saliidaha hydrocarbon badan si loo hagaajiyo saliidda saliidda heerkulka sare iyo hoose iyo in ay awood saliid in ay si fiican u shaqeyso labadaba xaaladaha taagan iyo kuwa firfircoon labadaba.
Rabadhka Ethylene propylene wuxuu u baahan yahay awood dhumuc sare leh, dhibic hooseysa iyo tusmada xasiloonida xiirid hoose marka loo isticmaalo wax ka beddelka saliidaha, shidaalka iyo naaftada.

Waxaan ku talinaynaa:
