PTFE Stirring Rod

PTFE Stirring Rod is a chemical-resistant mixing component designed for stirring, blending, and processing corrosive or high-purity liquids in laboratory and industrial applications. Manufactured from polytetrafluoroethylene (PTFE), it provides excellent chemical resistance, a non-stick surface, low contamination potential, and reliable performance across a broad temperature range.

JAIFUXIN manufactures PTFE Stirring Rods with Two-Blade and Four-Blade designs for different mixing requirements. Rod diameter, shaft length, blade size, blade configuration, and connection structure can be customized according to the mixing vessel, equipment design, and operating requirements.

Also referred to as a PTFE Stirrer, PTFE Stirring Paddle, PTFE Stirring Shaft, or Teflon Stirring Rod, this product is widely used in chemical laboratories, semiconductor processing, pharmaceutical production, chemical mixing, and corrosion-resistant process equipment.

Two-Blade and Four-Blade PTFE Stirring Rods

JAIFUXIN offers two primary blade configurations.

Two-Blade PTFE Stirring Rod

The Two-Blade PTFE Stirring Rod features two opposing blades attached to the stirring shaft. Its relatively simple structure provides effective fluid movement while maintaining low resistance during rotation.

Two-blade designs are suitable for many general-purpose mixing applications and can be customized according to vessel diameter and required mixing characteristics.

Typical advantages include:

• Simple and lightweight structure
• Good fluid circulation
• Lower rotational resistance
• Easy to clean
• Suitable for general chemical mixing
• Custom blade width and angle available

Four-Blade PTFE Stirring Rod

The Four-Blade PTFE Stirring Rod uses four blades arranged around the stirring shaft to provide more distributed contact with the liquid.

This design can provide stronger and more uniform fluid movement in applications where broader mixing coverage is required.

Typical advantages include:

• Four-blade mixing structure
• Broader mixing area
• More uniform liquid circulation
• Suitable for larger mixing vessels
• Good mixing performance for many process liquids
• Custom blade dimensions and angles available

The appropriate blade configuration depends on vessel dimensions, liquid viscosity, stirring speed, required circulation pattern, and process conditions.

Product Specifications

Dimensions and structures can be manufactured according to customer drawings, samples, mixing equipment, or vessel specifications.

Key Features

PTFE stirring rods are designed for mixing systems where conventional metal stirrers may be affected by corrosion or where direct metal contact with the process liquid is undesirable.

Key features include:

• Excellent chemical resistance
• Two-blade and four-blade options
• Excellent resistance to corrosion
• Smooth, non-stick PTFE surface
• Low surface adhesion
• Easy to clean
• Very low moisture absorption

• Custom connection structures available

Typical Applications

PTFE Stirring Rods can be used for mixing corrosive, sensitive, or high-purity liquids in laboratory and industrial equipment.

Typical applications include:

• Chemical mixing
• Acid and alkali solutions
• Laboratory reactors
• Chemical reaction vessels
• Semiconductor chemical processing
• Pharmaceutical processing
• High-purity chemical preparation
• Sample preparation
• Chemical synthesis
• Industrial laboratory equipment
• Corrosion-resistant mixing equipment
• Research and development
• Specialty chemical processing

PTFE Stirrer for Corrosive Chemicals

Chemical resistance is one of the main advantages of a PTFE Stirrer.

PTFE provides excellent resistance to a broad range of acids, alkalis, solvents, and aggressive chemicals. This makes PTFE stirring components particularly useful where stainless steel or conventional plastic stirrers may have chemical compatibility limitations.

The smooth PTFE surface also reduces material adhesion, helping simplify cleaning between mixing processes.

Chemical compatibility should be evaluated according to the specific chemical, concentration, operating temperature, stirring speed, and process conditions.

PTFE Stirring Rod for High-Purity Applications

For semiconductor, pharmaceutical, analytical, and other high-purity applications, controlling the materials that come into contact with process liquids can be critical.

A PTFE Stirring Shaft and Paddle provides a chemically resistant wetted surface without exposing the process liquid directly to conventional metal stirring components.

JAIFUXIN can manufacture custom PTFE stirring components according to customer requirements for material grade, dimensions, surface condition, cleaning, and packaging.

Custom PTFE Stirring Rod Manufacturing

Mixing equipment often requires stirring components designed specifically for the vessel and drive system.
