Product Description

PFA Rod

PFA rod is a high-performance fluoropolymer round bar designed for machining chemical-resistant, electrically insulating and high-purity components.

It combines excellent chemical stability with good temperature resistance, low moisture absorption and a smooth, non-stick surface. Compared with conventional engineering plastics, PFA is particularly suitable for components that may come into contact with corrosive chemicals, high-purity fluids or demanding process environments.

Our PFA rods are available in natural translucent color, with diameters from approximately 1 mm to 300 mm. Custom diameters, lengths and machined components can be produced according to drawings or application requirements.

PFA rod can be machined into seals, valve components, insulating parts, bushings, sleeves, connectors, laboratory components and precision parts used in semiconductor, chemical, medical, aerospace, automotive and industrial equipment.

Available Dimensions

For non-standard sizes, the final diameter, length, tolerance and production method should be confirmed before quotation.

Material Characteristics

Chemical Resistance

PFA provides strong resistance to many acids, alkalis, solvents and corrosive process chemicals. It is suitable for components exposed to aggressive chemical environments.

Final compatibility should be confirmed according to:

• Chemical type
• Chemical concentration
• Operating temperature
• Exposure time
• Mechanical load
• Cleaning process

Temperature Resistance

PFA offers good performance over a broad temperature range. The actual allowable operating temperature depends on the material grade, component design, mechanical load and service conditions.

Electrical Insulation

PFA has good dielectric properties and can be used for electrical and electronic insulation components.

High-Purity Performance

Its clean material characteristics and low moisture absorption make PFA suitable for selected semiconductor, laboratory, pharmaceutical and high-purity fluid-handling applications.

Machinability

PFA rod can be machined into custom components by turning, drilling, milling and other precision-machining processes.

Because PFA is softer than many rigid engineering plastics, machining parameters, clamping force and dimensional tolerances should be carefully controlled.

Typical Applications

PFA rod can be used to manufacture:

• Sealing components
• Valve seats
• Bushings and sleeves
• Insulating components
• Chemical-resistant connectors
• Pump and valve parts
• Laboratory equipment parts
• Semiconductor equipment components
• High-purity fluid-handling parts
• Precision-machined rings and spacers
• Automotive fluid-system components

Application Industries

• Semiconductor manufacturing
• Chemical processing
• Pharmaceutical equipment
• Medical equipment
• Electronics and electrical systems
• Aerospace equipment
• Automotive manufacturing
• Precision machinery
• Laboratory instruments
• Fluid-control equipment

Suitability for medical, food-contact or semiconductor applications depends on the exact raw-material grade, cleanliness level and required documentation.
