Matt, Sorry. I am of the 'old' school. Always think in Imperial terms. (eg; degs F). Paper burns @ 451 degrees F.... 150degs F wont hurt it/them. I think it's a synthetic fibre of some kind....
ps. There was a picture made,quite a few years ago called, 'Farenheit 451'. The 'firemen' went around burning books. Strange show!
