Propylene(C3H6) - is a colorless, flammable, liquified gas with a faintly sweet odor, so like natural gas it has Ethyl Mercaptan added which gives it its distinctive smell. Propylene has a higher overall temperature than propane and much lower temperature than acetylene.
Common uses of Propylene?
Propylene is primarily used in heating applications and as a hotter replacement for propane in heavy steel fabrication for heating and cutting.
