Antistatic PFA tubing-The “Safety Guardian” for flammable and explosive environments!

Our anti-static PFA tubing adds conductivity to high-performance PFA for chemical resistance and static dissipation.

It resists strong acids, alkalis, and solvents, performs from -80℃ to 260℃ without deformation or brittleness, and features a smooth, low-friction, non-toxic inner surface.
Its anti-static design prevents static buildup and sparks during fluid transfer.

Common sizes: 1/4", 3/8", 1/2", 3/4", 1" and more.

Widely used in semiconductors, chemical & pharmaceutical industries, labs, photovoltaics, and more

From hazardous chemicals to electronics, PFA anti-static tubing ensures safe fluid transfer.

Get to Know PTFE Sheets from Dankai

PTFE sheets is made from polytetrafluoroethylene resin through molding and sintering. As a widely used fluoropolymer sheet

PTFE offers top-tier performance,chemical stability, wide working temperature,low friction, and superior electrical insulation. They are also non-stick, weather-resistant, aging-resistant, and biocompatible

Thanks to these features, PTFE sheets are used in many industries.
Chemical: Protect equipment from corrosion
Mechanical: Reduce wear and friction
Electronics: Ensure electrical safety
Food Processing: Easy to clean and sanitary
Medical: Safe and reliable due to biocompatibility

PTFE sheets provide reliable solutions for corrosion protection, friction reduction, and insulation—an essential high-performance material in industry.

Standard FEP Tube or FEP Colored Striped Tube?

Standard FEP tubing has no markings, so multiple lines can be easily confused.

FEP colored striped tubes add built-in visual identification.
They cost slightly more than standard FEP, but make installation and maintenance much easier.

What do the stripes help with?
• Identify media, flow direction, pressure, or circuits by color
• Recognize tube size or application through stripe color or number
• Visually track fluid position or tube length in some systems

A small design detail that makes a big difference in complex setups.

PFA Welding Rod Process

1.Round Welding Rods: Use round nozzle; workpiece bevel 30–45°, welding speed 10–20 cm/min; rod must fit with seam; operate easily

2.Flat Welding Rods: Use flat nozzle; bevel 20–30°; welding speed 15–25 cm/min; rod must fit closely to seam; requires slightly more skill.

05/02/2026

How to choose PFA Welding Rods?

1.Round Welding Rods: For general, simple seams like pipe-to-pipe or straight-line welds; easy to operate.

2.Flat Welding Rods: For sheet welding, equipment corners, or seams requiring high flatness/sealing(semiconductor or pharmaceutical ultra-pure equipment)

3.Ultra-Pure Applications: Flat welding rods are preferred,seams are smooth with no dead zone, reduce particle buildup and fluid stagnation, ideal for high-purity process equipment

How Can PFA Flat Welding Rods Enhance Welding Efficiency?

Welding Process:

🎯Equipment: Hot-air welder at 350–400℃, flat nozzle.
🎯Pre-treatment: Apply 20–30° bevel, clean with ethanol, dry in dust-free room.
🎯Core Parameters: Weld at 360–380℃, speed 15–25 cm/min.
🎯Post-treatment: Cool for 30 minutes naturally.

how does this welding process translate to practical benefits?

For bevel seams and tight seams, the flat rod provides an even weld with minimal excess material.

Equipment corners become easier to manage, reducing the number of weld passes needed.

In ultra-pure environments, the welding rod ensures smooth, clean seams, perfect for semiconductors and pharma.

For industries requiring high-precision welding, PFA flat welding rods offer the perfect balance of performance and efficiency.

Sizes Available:12×2.5 mm，14×2.5 mm，17×2.5 mm

Why Choose PFA Flat Welding Rods?

High Fit: Perfect for welding corners, bevels, and seams.

Efficient Welding: Covers more area, reducing the need for multiple welds.

Even Forming: Ensures smooth seams without excess material or grinding.

Ultra-pure and clean: Produced in cleanrooms, with no impurities or bubbles.

For consistent, high-quality welds, PFA flat welding rods are the top choice for critical applications that demand reliability and precision.

What Is a PFA Welding Rod?

A PFA welding rod is a thermoplastic fluoropolymer consumable used for welding PFA materials.
Made from Perfluoroalkoxy , it can be melt-welded to form joints that match the base material.

• Temperature range: –80 °C to +260 °C
• Excellent resistance to strong corrosion
• Transparent or translucent, smooth surface
• No impurities, no bubbles

With good melt flow, welded joints reach ≥ 20 MPa tensile strength, remain pinhole-free, and resist vacuum and pressure.

Compared with FEP welding rods, PFA offers higher temperature resistance and stronger joints.Designed only for PFA welding.
