Features

1. High temperature resistance: working temperature up to 260 ° C
2. Anti-aging: can be used outdoors for a long time.
3. Corrosion resistance: resistant to most chemicals and solvents.
4. High lubrication: small friction coefficient (0.04) not change with temperature, PFA is a very good self-lubricating material.
5. Non-stick: with a small surface tension, the inner wall of the tube is not easy to adhere to colloids and chemicals.
6. Excellent electrical performance: PFA is a highly non-polar material with good dielectric properties, high electrical resistance and a dielectric constant of about 2.0. It is an ideal C-grade insulating material.

Important Considerations of PFA Welding Rods

 

High Purity PFA Welding Rods

Ventilation

Adequate ventilation is essential due to the high temperatures involved.

DN 5mm PFA Welding Rods

Material Purity

PFA rods are often made from ultra-pure PFA resin for demanding applications like semiconductor manufacturing.

DN 4mm PFA Welding Rods

Properties

Welded PFA maintains its wide temperature range (around -200°C to +260°C) and excellent chemical resistance, making it ideal for harsh environments.

 

 

FAQ

 

Q: What is the temperature of PFA lining?

A: The PFA lining can be used up to an operation temperature of 260 °C and is showing an excellent chemical resistance against condensation medias like H2SO4, HCl and HF, which are typically present in power plant applications.

Q: What is the difference between PFA and PTFE lining?

A: PFA is more flexible but has a lower flex-life, so it isn't as capable of enduring repetitive folding. PTFE has a slightly higher heat resistance but lacks when compared with the flow, creep resistance, and thermal stability.

Q: How long can a Pfa be at room temperature?

A: Store at room temperature. Unopened bottles are stable for at least 5 years when stored as recommended. After opening, bottles can be stored tightly sealed at 4°C for at least one month, or as long as no precipitation is observed.

Q: What is PFA material used for?

A: PFA is generally used for plastic lab equipment because of its extreme resistance to chemical attack, optical transparency, and overall flexibility. PFA is also often used as tubing for handling critical or highly corrosive processes. Other applications for PFA are as sheet linings for chemical equipment.
