PTFE is generally considered a thermoplastic polymer; at 327°C it maintains a very high viscosity, thus requiring particular transformation techniques for manufacturing of finished and semi-finished goods.

PTFE can be used at any temperature from -200°C to +260°C peter
Erm. We're talkng about use as a spacer in a headshell here. No extreme conditions involved (I hope).
