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 primarily 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 guildline 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 guide line only. The calculation is at ambient room temperature. It does not factor steam pressure, altitude, etc.
B=T(O.D.2 - I.D.2)
O.D.2 + I.D.2
B=Burst Pressure
T=Tensile Strength Values: FEP-3000 psi PFA - 4000 psi PTFE - 2500 psi PVDF - 5000 psi ETFE=6500 psi
1 bar = 14.504 ps |
