Basic features of PTFE:

PTFE (Teflon) is a fluorocarbon based polymer and typically is the most chemically resistant of all plastics, while retaining excellent thermal and electrical insulation properties. PTFE also has a low coefficient of friction so it is ideal for many low torque applications.
This material is non-contaminating and accepted by the FDA for food applications. Although the mechanical properties of PTFE is low, comparing to other engineered plastics, its properties remain useful over a wide temperature range.
Temperature range: -38°C to +230°C.
Color: white
Torque adder: 0%
