Superior Chemical Resistance
PTFE is inert to nearly all chemicals, acids, bases, and solvents – ensuring long‑term reliability in aggressive environments.
✔
Exceptional Flexibility
Flexible PTFE tubing resists kinking and blockage, maintaining consistent flow in complex routing applications.
✔
Excellent Dielectric Properties
High dielectric strength and low dissipation factor – ideal for wire insulation and electrical applications.
✔
Smooth Internal Surface
Ultra‑smooth bore minimizes pressure drop, prevents particle buildup, and allows easy insertion of components.
✔
Low Coefficient of Friction
Self‑lubricating surface reduces drag and wear – ideal for applications requiring low resistance to motion.
