The friction and wear behaviour of contacting materials vary greatly depending on the application in which they are used. Whether it is the applied load, sliding velocity, or change in contacting surfaces, such influences may have a significant impact on the wear performance of a material. This raises the need for solutions that can inherently minimise friction and resist external influences, thus reducing the required driving force and maintenance.
Low-friction plastics are self-lubricating materials with outstanding slide properties, resulting in perfect gliding performance. Here is how such materials stand to be vital solutions in demanding application areas, such as conveyor systems, bearings, and industrial machinery.
Many industries and application areas require materials with good slide properties that can withstand high loads and continuous contact. Conveying systems, for instance, undergo a wide range of loads under varying conditions, which can highly affect the friction behaviour of the materials. Bearings, rollers, gears, and other automotive parts also demand suitable slide properties and particular mechanical properties, such as high impact resistance.
And the list goes on. Any application area with moving parts would require either sufficient lubrication that can minimise wear and friction or materials with sufficiently good friction properties to maintain their performance and withstand the external influences.
Self-lubricating plastics intrinsically have very low coefficients of friction. With their good anti-adhesion properties, they enable the contacting parts to move smoothly and continuously without falling under the stick-slip effect. With that in mind, Murdotec Kunststoffe has developed a low-friction plastic material as a solution for many operational issues, allowing for perfect gliding optimisation.
Murdotec® 2000 MC is an ultra-high-molecular-weight polyethylene (UHMWPE) from Murdotec Kunststoffe. UHMWPEs are a family of thermoplastics with high fracture toughness, low friction coefficient, and high resistance to wear and abrasion. They have remarkable tribological characteristics and excellent impact resistance, even at extremely low temperatures, putting them ahead of stainless steel. They are also chemically inert, water-resistant, and good insulators of heat and electricity.
These characteristics have made UHMWPEs suitable materials for a huge variety of applications, particularly those requiring low friction, high durability, and good chemical resistance. Being a self-lubricating material, Murdotec® 2000 MC has found its way into applications as demanding as the displacement and construction of a 60-ton steel bridge.
In the town of Erkner, Germany, the railway has been a significant element for a long time. A double-tracked railway bridge crosses the Flakenkanal, a river that passes through the town connecting the two lakes, Flakensee and Dämeritzsee. However, this old timber-framed bridge has suffered from deterioration, and its restoration has been deemed costly.
So, a decision was made to replace it with a new steel-framed bridge. In order to do so, the steel framework had to be transported from the riverbank where it was resting onto a pontoon until it reached its provisional support point on the other side of the river. A hydraulic cylinder pushed forth the framework from the edge of the bank onto the pontoon.
So as to facilitate the displacement of the 60-ton-weighing steel framework, Murdotec® 2000 MC came into play. With its anti-adhesion and self-lubricating properties, Murdotec® 2000 MC played the role of a supportive gliding material, minimising friction and allowing the framework to slide much more easily onto the pontoon.

The table below shows key properties and characteristics of Murdotec® 2000 MC that have allowed it to be the material of choice for such an application.

Murdotec® 2000 MC is a material with perfect gliding optimisation. Its sliding properties significantly reduce the required driving force and energy while maintaining a higher slide speed. Consequently, this brings about a lower need for maintenance and higher productivity. All this is the result of Murdotec Kunststoffe’s years of experience in developing and producing high-quality materials.
Murdotec Kunststoffe is a trusted supplier and manufacturer of technical thermoplastics based on polyethylene (PE). They enhance the quality of their PE materials, particularly HMWPE and UHMWPE, via sophisticated recipes that help boost the material properties. Based in Germany, they provide their customers with semi-finished products and advise them on how to best use those products.
Today, Murdotec Kunststoffe have partnered with Matmatch to bring their materials and services one step closer to engineers and product developers searching for high-quality polyethylenes with distinct properties, such as self-lubrication. Their materials are available in sheet and rod forms and have the required quality, safety, and sustainability certifications (ISO 9001:2015, ISO 50001, ISO 14001:2015).
Highest demands in production and consulting
Everything at Murdotec revolves around polyethylenes. These are subdivided into groups with defined minimum requirements for better distinction and have been named HD-PE, HMW-PE and UHMW-PE.
As a manufacturer based in Germany, we are able to guarantee that our semi-finished products are of the highest quality – thanks to the targeted choice of selected raw materials as well as continuous monitoring during production and the composition of recipes.
We advise our customers in choosing the semi-finished products that offer the desired properties that will suit their needs. But our work does not end with the shipping of the ordered goods. We will work with you on request to develop individual solutions and advise you on the best way to use our semi-finished products.
Murdotec only uses HMW-PE- and UHMW-PE-group polyethylene. The quality of a UHMW-PE as per ISO 15527 is largely guaranteed by the basic material and processing parameters. Murdotec significantly improves this quality by using sophisticated recipes from its own laboratory to considerably enhance the plastics’ properties. In addition, EC regulations define application limits by requiring certification as per Regulations (EC) No. 1935/2004 and 10/2011 for plastics that come into contact with foods that have not yet been packaged, for example.
We rely on such innovative production technologies as the latest computer-controlled and monitored press lines and environmentally-safe raw-material handling.
The result is an extensive product range consisting of sheets, pre-cut parts, and rods. Whatever the sector – machine construction, conveyor technology, lining and bulk material handling or the paper, food, or forestry industries – we’ve got the right type of plastic for you!
Our technical UHMW-PE materials Murdotec® 1000, and Murdotec® 2000, our technical HMW-PE material Murdotec® 500, and our plastics in the LM family – which are approved for use in the food industry – are even better than semi-finished products as per ISO 15527. Why?
