The Pyrolysis of Inorganic Fire Retardant Polyolefin Cable Materials

The Inorganic Fire Retardant Polyolefin Cable Materials is analyzed with thermogravimetric and differential scanning calorimetry (TG-DSC) in this paper. The result indicates that there are three stages in the pyrolysis process: 260∼330 ̊C, 330∼400 ̊C, and 400∼500 ̊C. Active energy E and antecedent A in each stage are calculated. And reaction in the first and third stages can be treated as first order reaction.
