PTFE

PTFE laser cut sample

Polytetrafluoroethylene

Laser cut material PTFE is one of the most chemically resistant polymers.

Applications

Fluorinated thermoplastics are only used for high performance applications related to high heat, low temperature, chemical inertness, high purity, non-sticking and self-lubricating properties.

Properties

It has excellent electrical properties including high insulation resistance, low dielectric constant and high thermal stability. It also has excellent properties such as chemical inertness, heat resistance (both high and low), electrical insulation properties, low coefficient of friction (static 0.08 and dynamic 0.01), and nonstick property over a wide temperature range (260 to 260°C).
