Specifications of PTFE

Low coefficient of friction

PTFE is renowned for its low coefficient of friction, making it an excellent solid lubricant. This property is crucial for applications where reducing friction is essential.

Dielectric properties

PTFE boasts exceptional dielectric properties, maintaining stability across various temperatures and frequencies. That makes it ideal for electrical applications where insulation and stability are critical.

Chemical and thermal resistance

PTFE shows exceptional resistance to high and low temperatures, enduring up to 260°C without significant changes in its properties. It also withstands nearly all chemical agents, maintaining its integrity even in the most aggressive environments.

Applications of PTFE bars and rods

Chemical industry

In the chemical industry, PTFE is used to make gaskets and components that come into contact with corrosive agents like concentrated sulphuric acid. It is also chosen to coat surfaces exposed to aggressive substances, providing superior protection thanks to its chemical inertness and resistance.

Electrical applications

PTFE is widely used in the electrical industry as an insulating material due to its exceptional dielectric properties.

It is used to coat cables and electrical components, ensuring insulation and stability even in extreme temperature conditions.

Mechanical engineering

In the mechanical sector, PTFE reduces friction in components such as bearings and seals. Its low coefficient of friction and thermal resistance make it ideal for applications requiring durability and minimal maintenance. PTFE is also utilised in injection systems and engines to improve efficiency and reduce wear.

How to choose PTFE Bars and Rods

1. Dimensions and diameters

When selecting PTFE bars and rods, it’s essential to consider the dimensions and diameters that fit your project’s technical requirements. You can customize the cutting of the bars to purchase only the amount you need, and additional cuts can often be done at no extra cost, allowing you to receive the material already cut to the desired dimensions. Tolerance and weight are crucial for rods and vary depending on the diameter. Options typically range from 6mm to 200mm in diameter, with standard lengths of 1000mm or 2000mm.

2. Quality of the material

The quality of the PTFE used in the bars and rods is crucial for their performance. Selecting top-quality virgin non-reclaimed materials ensures the best wear resistance and sliding properties. PTFE is known for its excellent specs, such as non-toxicity, chemical inertness, workability, and non-stick properties, which are essential for many industrial applications.

3. Price and availability

While PTFE may be more expensive than other plastics, its durability and superior technical properties justify the investment. Check the availability of the required dimensions and shapes, such as perforated bars or sheets, and consider the possibility of custom orders to meet your specific project needs.

Benefits of using PTFE

PTFE is renowned for its exceptional resistance to ageing and UV rays, ensuring long-lasting performance even in extreme conditions. It is also highly safe for food use, being non-toxic and approved for direct contact with food in many countries.

One of the standout features of PTFE is its ease of processing and maintenance. Its non-stick surface prevents build-up and makes cleaning effortless, reducing maintenance costs and enhancing its versatility across various industrial applications.

While PTFE may have a higher initial cost than other materials, its durability and superior performance make it a perfect investment. Its wide-ranging applications in mechanics, electronics, and the chemical industry highlight its versatility and ability to meet specific needs. Additionally, on-going research and new applications continue to push the boundaries of innovation, promising benefits in the future.
