Murdotec Kunststoffe GmbH & Co. KG
Industrial operations that involve production lines require materials with a unique set of properties to maintain a continuously functioning process. The beverage industry is no stranger to such operations, as it demands special materials for its filling lines with particular properties like wear resistance, anti-adhesion, and shock absorption. Here, we present an exceptional, ultra-high-molecular-weight polyethylene (UHMWPE) material, called Murdotec® 1000 black AST, as a material of choice for such applications. We especially highlight how one winery has adopted this technical thermoplastic into all its filling lines.
In Zell, Germany, a large winery that exports beverages to over 35 countries has landed the opportunity to use an ideal material for its format sets on the production line as part of an important maintenance project. Supplied by a thousand winegrowers, this winery required complex-shaped format sets that allowed for different bottle shapes and faster delivery.
As part of the process, the winery began taking into consideration the different factors that can influence their material selection. Their communication with Murdotec Kunststoffe made their decision making much easier with Murdotec’s engineering assistance and valuable advice.
Murdotec Kunststoffe is a supplier of technical thermoplastics, particularly UHMWPE. They manufacture a huge variety of complete format sets specifically made for the food, beverage, and pharmaceutical industries. These include conveying screws, conveyor star wheels, and sliding return channel components.
Considering the required material properties to enable format sets at different stages of the production line to function continuously, the winery selected the UHMWPE Murdotec® 1000 black AST due to its exceptional features, particularly its wear resistance, chemical inertness, and high impact resistance.
Despite its compliance with the FDA and EU’s regulations for food contact materials, there was no need to consider this aspect here as there was no contact between the foodstuff and the material itself. The contact remained at the level of the bottles in all format sets in the rinser, filler, corker, capper, capsule applicator and labeller equipment. In addition, Murdotec® 1000 black AST provided protection against potential electric charging during labelling thanks to its antistatic properties and against possible UV light due to its UV stability.
Ultra-high-molecular-weight polyethylene (UHMWPE) is a polyolefin material with long chains of polyethylene (PE) that provide sufficient strength, fracture toughness, and impact resistance. This low-density plastic exhibits chemical and surface properties that are not as common in high-performance polymers. It is highly resistant to water and moisture with an extremely low friction coefficient and excellent wear behaviour, not to mention its insulation properties against heat and electricity.
This enabled UHMWPEs to be materials of choice in multiple industries, including the food industry, electrical engineering, transportation and conveyor technologies.
Murdotec® 1000 black AST is an exceptional UHMWPE with antistatic properties, perfect for applications requiring high mechanical and sliding properties. With a molecular weight of 5,000 kg/mol, quality approval by the FDA and the EU, and compliance with ATEX 95, this material is quite ideal for conveyor systems, sliding applications, bearings, control discs, and food/beverage filling equipment. It is available as semi-finished products in sheet, pre-cut parts, and rod forms.

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.
Top-quality PE
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?
