| Popis: | When polytetrafluoroethylene (PTFE) was pyrolyzed in air in the temperature range of 500° to 650°C (932° to 1202°F), the predominate product was COF2. Above 650° C the major products were CF4 and CO2. Other fluorocarbons were produced in lesser amounts. PTFE pyrolyzed in the presence of SiO2 also formed SiF4. Between 550° and 600°C production of COF2 was as high as 63%. Experimental exposure of rats showed COF2 to be the most toxic component of the pyrolysis gases. |
