PVDF Tubing (Polyvinylidene Fluoride) is an abrasion resistant fluoropolymer suitable for use in applications requiring chemical resistance with low permeability. PVDF Tubing is often referred to by its trade name, KYNAR®, and is designed prmarily for applications requiring excellent chemical resistance, high levels of purity and superior mechanical properties. PVDF Tubing is often used as a lining or protective barrier in chemical industry applications and is just as useful in ultra pure water systems and ground water monitoring.
PVDF Tubing Offers:
- Excellent abrasion resistance
- Excellent resistance to creep and fatigue
- Low permeability
- Good chemical resistance
- Excellent thermal stability
- Excellent radiation resistance
- Excellent resistance to cut-through
PVDF Tubing Applications:
Aerospace &Transportation Technology, Electronics, Components &
Insulators, Chemical & Pharmaceutical Manufacturing, Food
Processing, Environmental Sciences, Air Sampling, Fluid Transfer
Devices and Water Processing Systems

* This tubing has
a safety factor of 5 to 1 (ratio of burst pressure to working
pressure). This data is to be used as a guildeline only. You should
perform actual tests according to your specific application.
** The following equation is for
calculating burst pressure. The result from this equation is to be used
as a guideline only. The calculation is at ambient room temperature.
It does not factor steam pressure, altitude, etc.
