Murtfeldt – Innovationen für die Zukunft Murtfeldt – Innovations for the Future Mit der Entwicklung von Werkstoff ”S”® Grün setzten wir im Jahr 1958 richtungsweisende Maßstäbe. Wir wussten damals, dass die Entwicklung moderner Fertigungsanlagen künftig komplexe Anforderungen an Bauteile und deren Materialien stellen würde. So gelang es uns, ein Material zu entwickeln, das bis heute in Sachen Abriebfestigkeit und Gleiteigenschaften zum weltweiten Standard wurde. In developing the Murtfeldt Material ”S” ® green in 1958, we set a standard. We already knew at the time that the development of...

Original Material ”S” ®  Working without static Special demands are placed on materials in environments where sparks could cause explosions. Thanks to the highly conductive properties of ”S”® plus+ ESD, the material results in a complete discharge of any static load along the material surfaces and ensures a spark-free and safe working environment. The material therefore constitutes an economical alternative to carbon-filled PTFE. + Extremely good conductivity (surface resistance ≤ 104 ohm) + Static discharge at the surface in less than 0.1 seconds + Economical alternative to carbon-filled...

Original Material ”S” ®  Clean application Bright surfaces are essential in many working environments since dirt and dust particles must be visible so that required hygiene levels may be satisfied. Until now, it has been impossible to produce a material that meets the necessary colour requirements and also offers high conductivity. ”S” ® plus+ Bright ESD is the first bright coloured plastic to be developed that is also highly conductive, which means that electrical charges can be dissipated on earthed components. The material is ideally suited for use in areas where hygiene and anti-static...

Sterile and safe Properties Microbes (e.g. micro-organisms such as bacteria and fungi) can damage the human body. They should therefore be prevented in food production and processing. ”S”® plus+ AB contains special substances that prevent bacterial and microbial growth while simultaneously protecting people and the environment. Microbial growth on this materials surface is reduced by at least 99.96% compared with materials without additives; this prevents both unpleasant odours and the buildup of biofilm. ”S”® plus+ AB combines its antimicrobial effect with the excellent properties of the...

Properties Many industrial applications take place at higher temperatures that ”S”® materials could previously not withstand. Such applications require materials that possess familiar properties such as wear resistance, high impact strength, and resistance to chemicals. Murtfeldt has now created Original Material ”S”® plus + TLS, which can be used in areas where it was previously not possible to use the ”S”® family materials. The molecular structure of this ultra-high molecular weight low-pressure polyethylene does not change even if exposed to high constant operating temperatures of 100°C...

Introducing: „Low Friction" Properties Murtfeldt‘s response to international demands for lower energy consumption and sustainability: Original Material ”S”® plus+ LF. With this material, Murtfeldt has been able to further slash the sliding friction coefficient by half again. And what is outstanding here is that the value is constant and is achieved even at low friction intensities. The material drastically reduces the necessary driving forces so motors need less energy and accordingly run more economically. The new material therefore enables machines to run at higher speeds while...

Original Material ”S” ®  Highest efficiency The use of this new material saves energy and – thanks to its low frictional resistance – increases the efficiency of your machines. The material reduces the sliding friction coefficient by up to 50% – thus resulting in an equivalent reduction in the energy needed for the required drive power. The material therefore offers great savings potential. Thanks to the additive used, Original Material ”S”® plus+ LF ESD is also electrically conductive and therefore allows electricity to be eliminated as quickly as possible while achieving minimum friction...

Original Material ”S” ®  Top-quality „food protect“ Original Material ”S”  plus+ FP [FS] is a new technical plastic that completely meets the requirements of the food sector for the detectability of plastic foreign bodies in foods.
“FP” stands for “food protect” and embodies two vital properties: This product is both food-safe and metal-detectable. Metallic foreign bodies in foods are safely detected by metal detectors and removed. However, plastic particles from plant components can be problematic. Thanks to the use of additives in Original Material ”S”® plus+ FP [FS], all commonly used...

Practically no wear This material is used for applications that involve manufacturing and transportation at high pressure. The balanced quantity of micro glass beads in Material ”S”® plus+ GB provides the combined benefits of extremely high molecular weight polyethylene and glass. The glass beads that protrude from the surface give a rounded and hard sliding surface. Properties + Protects the sliding partner (unlike glass-fibre reinforced plastics) + Extremely good resistance to chemicals + Approved for use in the food industry (EU and FDA) Application areas + Guides for PET bottlenecks in...
