The mfg web site claims 300F.

Quote:
The gel-spinning process and subsequent drawing steps allow SpectraŽ fiber to have a much higher melting temperature (150°C or 300°F) than standard polyethylene.


This jives with what Tom Moyer's study states:

Quote:
The melting point is very low, 147 C or 297 F, not much warmer than boiling water.


Compare to Kevlar (~932F) or Technora ~900F.

If I recall my Ray Bradbury, paper burns at 451F, so therefor it makes sense that it should be possible to melt Spectra with an open flame.

Also note that in the link you provided, they refer to Maxim as a Spectra product, but as we found, Maxim appears to be the name of a New England Rope Technora product, not a Spectra product.
