CFCs Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. It is the chemicals that break down ozone in the troposphere.
CFC’s is Chlorofluorocarbons which is totally different chemical structure from polystyrene. CFC’s has very low blowing point and uneasy to be maintained in EPS beads. Therefore, EPS Foam never use CFC’s at any stage of its production.  1 Though polystyrene manufacturers claim that their products are ozone-friendly or free of CFCs, this is only partially true. 2  Some polystyrene is now manufactured with HCFC-22, which, though less destructive than its chemical cousins, CFC-11 and CFC-12, is still a greenhouse gas and harmful to the ozone layer. 1 The use of hydrocarbons in polystyrene foam manufacture releases the hydrocarbons into the air at ground level; there, combined with nitrogen oxides in the presence of sunlight, they form tropospheric ozone -- a serious air pollutant at ground level. Arctic Ozone Hole. CFCs Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. A common subclass is the hydrochlorofluorocarbons (HCFCs), which contain hydrogen, as well. Freon is DuPont's brand name for CFCs, HCFCs and related compounds.  0. A. No. None of the styrofoam products manufactured in America contain CFC's. In the production of polystyrene, emissions are carefully controlled to protect the environment. In fact, the polystyrene industry was first in the nation to voluntarily discontinue its already limited use of ozone-depleting CFC's in 1989.  The production of Styrofoam products used CFC’s. The use of CFC’s was banned in 1989 so many companies stopped using products made with Styrofoam including McDonald’s (voluntarily). Production methods changed so there was no longer CFC pollution in production but many of it’s ill effects remained.  2.0 CFCs. CFCs or HCFCs are found in extruded polystyrene foam boards, isocyanurate foam boards, phenolic foam boards, and polyurethane blow-in insulation. Expanded polystyrene rigid insulation at a higher density of 2 lb./ft3 (normal density is 1.0 lb./ft3) performs similarly to extruded polystyrene. A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon. The most common representative is dichlorodifluoromethane (R-12 or Freon-12).  Does polystyrene deplete the ozone layer? 1  Initially a portion of polystyrene production was aided by the use of chlorofluorocarbons (CFCs), the chemicals that break down ozone in the troposphere. 2  Though polystyrene manufacturers claim that their products are ozone-friendly or free of CFCs, this is only partially true. 1 The use of hydrocarbons in polystyrene foam manufacture releases the hydrocarbons into the air at ground level; there, combined with nitrogen oxides in the presence of sunlight, they form tropospheric ozone -- a serious air pollutant at ground level. Chlorofluorocarbons in Insulation Materials. Most rigid-board insulation is produced with CFC-11 or -12 as the blowing agent. Injected into the foam as a liquid during manufacturing, the CFC boils, causing gas bubbles to form in the curing foam. The cured foam has bubbles of CFC gas throughout. Tweet. UV light breaks a chlorine atom off a CFC molecule. The chlorine reacts with ozone (O3), forming molecular oxygen (O2) and chlorine monoxide. The oxygen is pulled off that molecule by a free oxygen atom, leaving the chlorine atom to start the process all over again. Polystyrene is a petroleum-based plastic made from the styrene monomer. Most people know it under the name Styrofoam, which is actually the trade name of a polystyrene foam product used for housing insulation. 1 The use of hydrocarbons in polystyrene foam manufacture releases the hydrocarbons into the air at ground level; there, combined with nitrogen oxides in the presence of sunlight, they form tropospheric ozone -- a serious air pollutant at ground level.
