// Definition
Polytetrafluoroethylene (Teflon) film used as a non-stick surface for collecting rosin and handling sticky hash concentrates. Rated to approximately 500°F, PTFE provides superior non-stick properties compared to parchment paper, allowing cleaner and more complete collection of pressed rosin. Not resistant to hydrocarbon solvents, limiting its use to solventless applications.
// From the Episode
PTFE film was discussed as the preferred collection surface for rosin pressing, replacing parchment paper for serious producers. The completely non-stick surface means virtually no oil is lost to the collection material. The temperature rating provides ample margin above the 300–400°F pressing range. The caveat about solvent incompatibility means PTFE should only be used for solventless processes.
