Various MSDS sheets show a range of autoignition temps for polypropylene. Ranging from 260 to 410 or thereabouts Celsius.
Any substance with a sufficiently large average molecular weight to be called "polypropylene" under normal circumstances is a solid at standard temperature and pressure. However, note that some hydrocarbons, such as hexenes, that could be formed by condensing small numbers of polypropylene molecules, are not solids at standard temperature and pressure.
The minimum temperature the fuel ignites self sustained combustion is known as spontaneous ignition temperature. The temperature at which the substance is preheated and burns smoothly is known as ignition temperature.
If the ignition temperature of a substance is lower than the room temperature where it is, then that substance ignites.
1100-1200 degrees Fahrenheit is the minimum ignition temperature.
Higher the glass transition temperature of the polystyrene can be attributed to the fact that sterically rigid bulky aromatic moieties like benzene in the styrene compared to that of aliphatic polypropylene
kerosene has got higher ignition temperature.

The softening temperature of polypropylene is 150 degrees Celsius. Its melting point is between 160 and 170 degrees Celsius.
Polypropylene is the most common form of synthetic material used. It is used in almost every thing we use. Though previously declared safe, recent searches reveal that polypropylene may release two highly toxic substances, quaternary ammonium biocides and oleamide.
Polypropylene is not dissolved in ethanol.
The abbreviation for polypropylene is PP.
Temperature can cause damage to the ignition coil. Temperature which is above 150 degrees Celsius can cause a great damage to it.
