PTFE, Molded

All SPI Supplies Brand PTFE tweezers are chemically inert, non-contaminating, and are thermally stable in the range of -200°C (390°F) to + 280°C (+536°F). The tweezers have a super smooth finish making it virtually impossible for anything to stick to their surfaces, either inside or outside.

Details of the manufacturing:

The SPI Supplies Brand PTFE tweezers are isostatically molded from pure virgin PTFE resulting in a highly inert material, one that will stand up to nearly every way one might want to use it. The tweezers are manufactured with two different end styles: flat platens and soon to be introduced, sharp tips.

Cautions about over heating:

PTFE tweezers can not be taken to temperatures as high as Pyrex® glass or some other materials. The user has to be sure they do not overheat these PTFE tweezers. If PTFE is overheated, especially in air, it can start to break down by both thermal decomposition and oxidation, resulting in fumes of HF which should not be inhaled under any circumstances. The very low extractables from the PTFE used for the construction means that there will be nothing leaching out of the PTFE itself and causing contamination of the materials being picked up with these tweezers.
