As a supplier of peek tubing, I often get asked whether peek tubing has low friction. It's a question that's crucial for many industries, especially those where smooth flow and minimal resistance are essential. In this blog, I'll dig deep into the world of peek tubing and explore its friction characteristics.
First off, let's understand what peek tubing is. PEEK stands for polyether ether ketone, a high - performance thermoplastic known for its excellent mechanical, chemical, and thermal properties. Our company offers a variety of peek tubing options, like Peek Capillary Tubing, Green Peek Tubing, and Peeksil Tubing. These products are used in a wide range of applications, from medical devices to aerospace components.
Now, back to the question: does peek tubing have low friction? Well, the answer is yes, and there are several reasons for this. One of the key factors is the molecular structure of PEEK. The polymer chains in PEEK are arranged in a way that provides a relatively smooth surface at the microscopic level. This smooth surface reduces the contact area between the tubing and the fluid or object passing through it, which in turn lowers the frictional force.
In addition, PEEK has a low coefficient of friction. The coefficient of friction is a measure of how easily one surface slides over another. A lower coefficient means less resistance and smoother movement. Compared to many other materials, PEEK's coefficient of friction is quite low, making it an ideal choice for applications where low friction is a must.
Let's take a look at some real - world examples to illustrate the low - friction advantage of peek tubing. In the medical field, peek capillary tubing is often used in fluid delivery systems. When delivering drugs or other fluids, it's important to ensure a smooth and consistent flow. The low friction of peek tubing helps to achieve this, reducing the risk of blockages and ensuring accurate dosing.
In the automotive industry, peek tubing can be used in fuel injection systems. The low friction of the tubing allows for more efficient fuel flow, which can improve engine performance and fuel economy. It also reduces wear and tear on the components, increasing the lifespan of the system.
Another industry that benefits from peek tubing's low friction is the semiconductor manufacturing. In semiconductor processing, precise control of fluid flow is crucial. Peek tubing's low friction helps to maintain the accuracy of fluid delivery, which is essential for producing high - quality semiconductors.
But the low - friction property of peek tubing isn't just beneficial for fluid flow. It also has advantages in applications where mechanical components move inside the tubing. For example, in robotic arms or other automated systems, peek tubing can be used to guide wires or other moving parts. The low friction allows these parts to move smoothly, reducing energy consumption and improving the overall efficiency of the system.
However, it's important to note that the friction of peek tubing can be affected by several factors. The surface finish of the tubing plays a significant role. A smoother surface finish will generally result in lower friction. Also, the type of fluid or object passing through the tubing can have an impact. Some fluids may have a higher viscosity, which can increase the frictional force. Temperature can also affect friction. At higher temperatures, the properties of PEEK may change slightly, which could potentially affect its frictional characteristics.
To ensure the best possible low - friction performance, we at our company take great care in the manufacturing process of our peek tubing. We use advanced machining and finishing techniques to achieve a high - quality surface finish. We also conduct rigorous testing to ensure that the tubing meets the required standards for low friction.


We offer different grades of peek tubing to meet the specific needs of our customers. For applications where extremely low friction is required, we can provide tubing with a special surface treatment or coating. These treatments can further reduce the friction and enhance the performance of the tubing.
