PTFE Thermal Stability ?
PTFE Thermal Stability ?
(OP)
Can anyone advise on the thermal and mechanical stability of PTFE at temperatures above 300C. Data sheets that I have seen, give the upper working temperature of the material to be 260C with a (Theoretical??) melting point of 327C. Dose the material melt? And does it give off any toxic fumes above the recommended upper working temperature.
Thanks in advance

RE: PTFE Thermal Stability ?
You need specific info on the PTFE (in particular manufacturer and their designation) to find the elevated temperature properties. Literature list hydrogen fluoride as a decomposition product of fire.

howver any load will cause cold flow or extrusion of the material.
