Classification of PTFE rods

Given different manufacturing techniques, PTFE rods can be divided into PTFE pressed rod, PTFE extruded rod and PTFE molding rod. PTFE pressed rod is produced by compressing PTFE powder into a preformed shape and then sintering it at high temperatures. PTFE molding rod is formed by compression molding PTFE resin into a rod shape using heat and pressure. PTFE extruded rod is manufactured by extruding PTFE resin through a die to form a continuous rod shape. Each type has different advantages and properties in terms of dimensions, surface finish and cost considerations.

What can PTFE rods be used for?

What can PTFE rods be used for?

PTFE rods have been applied in various industries ranging from aerospace and automotive to food processing and medical devices. Some of its  typical applications can be seen as the following:

Bearings and bushings: Given its low friction coefficient, it can be manufactured into bearings and bushings in the automotive and aerospace industries.

Electrical insulation: Due to its excellent electrical insulation property, it can be used as the insulating components such as spacers, cable coatings and connectors in the electronics industry.

Seals and gaskets: Taking its exceptional chemical resistance into consideration, it can be fabricated into seals and gaskets in oil and gas, chemical processing, and food processing industries.

Food processing equipment: Also, PTFE rods are employed in the food processing equipment such as seals, conveyor belts and components in contact with food due to its non-stick property.

What are the Characteristics and Advantages of PTFE rods?

What are the Characteristics and Advantages of PTFE rods?

Chemical resistance: PTFE rods exhibit high chemical resistance. It can be spared from chemical attack by some corrosive substances like acids, bases, and solvents. 

Low friction coefficient: It possesses an exceptionally low coefficient of friction, even in dry or non-lubricated conditions, which makes it an ideal material for reducing friction in the components that require smooth movement.

Non-stick properties: PTFE is non-stick in essence, which means that substance will not adhere to its surface. This unique property enables it to be unutilized in applications where the pile-up of materials should be minimized.

High temperature stability: PTFE rods can be subject to use under a wide range of temperatures (basically from a low of -200°C to a high of 260°C). This property makes it suitable for various applications.

Electrical insulation: PTFE also showcases excellent electrical insulation. It can be widely used in applications that set high requirements on electrical insulation.

Dimensional stability: PTFE is also equipped with stable dimensional performance, which means that it can maintain its shape and property under different temperatures, pressures and other conditions.

UV resistance: PTFE rod is also resistant to ultraviolet radiation, which makes it suitable for outdoor applications without severe degradation.

Is PTFE equal to Teflon?

Yes, PTFE (polytetrafluoroethylene) is commonly referred to as Teflon, and it is a registered trademark of the Comus Corporation. Teflon is a well-known brand name for PTFE, but PTFE itself is a generic term for the material.

Why is PTFE so expensive?

PTFE is so expensive due to its complex manufacturing process and unique chemical properties. As for the manufacturing process, it requires specialized equipment and careful control of temperature and pressure, which contributes to its production costs.
