Description

Ethylene appears as a colorless gas with a sweet odor and taste. It is lighter than air. It is easily ignited and a flame can easily flash back to the source of the leak. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Can cause explosion.;Ethylene, refrigerated liquid (cryogenic liquid) appears as a pressurized liquid when shipped below 50°F. Colorless with a sweet odor and taste. Vapors arising from the boiling liquid are lighter than air. Easily ignited. Not toxic but is a simple asphyxiant. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. Used as an anesthetic, a refrigerant, and to make other chemicals.;Polyethylene as is a white powder (microbeads). Tough and flexible at room temperatures.
