Ethylene, mpweya wopanda mtundu, amanyamula fungo lodziwika bwino la hydrocarbon yokhala ndi kutsekemera pang'ono.
Ndi yoyaka kwambiri, yokhala ndi kutentha kwa 425 ° C, malire kuphulika chapamwamba cha 36.0%, ndi malire otsika a 2.7%. Pamene ethylene akuphatikizana ndi mpweya, zimapanga chisakanizo chosasunthika chomwe chimatha kuphulika. Kuwonekera kwamoto wotseguka, kutentha kwakukulu, kapena zoyambitsa oxidizer kuyaka ndi kuphulika.
