Secure and compromissible quality


We put our materials to the test

Whatever you need or want to know about a material, we will find out. From extensive testing to specific inspections, we guarantee precision, reliability and uncompromising quality for your applications. For results you can rely on.

The performance of our materials is tested in a wide range of scenarios: In order to meet our customers specific requirements, we carry out standard tests in accordance with ISO standards as well as customised tests. From hardness testing and friction coefficient measurement to infrared spectroscopy, our aim is to accurately and reliably determine the performance characteristics of our materials at all times. This ensures that our materials meet our expectations for durability and quality.

An overview of our testing methods:

Density determination is a method of measuring the density of a material, which indicates how much mass is present in a given volume. The solid is immersed in a liquid and the displaced volume of liquid is equal to the volume of the solid. The mass of the displaced volume of liquid is then used to determine the density.

The impact test is a mechanical test used to determine the toughness of a material, in particular its ability to absorb energy during rapid fracture. An elongated, double-notched specimen is subjected to an impact load in a standard laboratory environment.

The coefficient of friction of a material is determined by measuring the coefficient of friction. It describes the relationship between two forces - the frictional force and the contact force. These occur when two bodies stick, slide or roll against each other. The test body is pressed against a base body with a defined normal force. The resulting frictional forces try to counteract this movement. This is followed by the long-term wear test, which helps to analyse how the coefficient of friction changes or adapts over a longer period of time.

Customised material development in our own laboratory

Every year, our laboratory launches an average of one new PE-based development. 90% of these newly developed materials are created in response to specific customer demand or requests. And this is how our material development process works as soon as a need has been identified and deemed relevant: Firstly, the special formulation is written in the laboratory, then initial samples are produced. If there is a match that fulfils all the desired properties, this formulation is initiated in an intensive test phase: This means there are test customers, trials in the actual application and, above all, regular consultation with the test customers or development partners. In addition, the performance of our materials is tested in a wide variety of scenarios in order to fulfil the specific requirements of our customers.

The ball indentation method was introduced to determine the hardness of materials. The method is based on measuring the depth of penetration of a steel ball into the surface of a test specimen under the effect of a test load. This test load is applied for a defined time after a preload has been applied. The fundamental difficulty with this method is that the depth of penetration is not a linear function of the load. This is compensated for by limiting the indentation depth to a value that is small compared to the ball diameter.

Shore durometer to DIN EN ISO 868, like many other hardness tests, measures the depth of an indentation in a material produced by a given force on a standardised indenter.

The sand slurry test is used to test the abrasion resistance of materials. The materials are exposed to an abrasive mixture of sand and water at high speed for 24 hours. This simulates the long life and wear behaviour of materials.

Versatile, powerful, forward thinking

Materials are more than just materials - they are the basis for innovative solutions in almost every industry. Whether it is maximum wear resistance, exceptional sliding properties or extreme resilience, our materials combine quality with functionality and set standards for efficiency and durability.

  • Temperature and chemical resistance
  • Lightweight construction and mechanical strength
  • Minimal wear and insulation
  • Food conformity & detectability

  • Corrosion and environmental resistance
  • Hygiene and recyclability
  • Sound and vibration damping
  • Durability and cost effectiveness

There are a number of effective ways to prevent electrostatic discharge, which can prevent sudden discharges from causing costly damage to electronic components and assemblies, or dust explosions. Murdotec's dissipative materials help to create a safe working environment by preventing or minimising charges by dissipating them or allowing them to discharge evenly.

Tensile testing is an essential method for determining the mechanical properties of materials. It provides important information about the behaviour of a material under tensile load, including tensile strength, elongation and modulus of elasticity. These properties are crucial for the selection and application of plastics in various technical and industrial fields. In our laboratory we can perform tensile tests on our plastics at temperatures ranging from 23°C to 250°C.

Metal detection tests the detectability of material residues. This feature is particularly important in the food industry.

Microscopic examination of materials allows the assessment of plastic moulded parts in terms of processing and stress. Microscopy provides essential information for the elimination of quality problems and their causes.

Infrared spectroscopy is a physical testing method that works with molecular vibrations using a Fourier transform infrared spectrometer. This method can be used to identify substances and determine material properties. An infrared laser is shone through the molecules and the range in which the bonds of the molecules vibrate is measured, absorbing some of the energy. The transmission, i.e. the unabsorbed energy of the laser, is then determined and displayed in the form of a spectrum. The resulting spectrum is molecule specific, so each substance has a unique band pattern. These spectra are compared with each other using a matching system to identify materials against references.

The Load Cycle Tester is a practical endurance test developed as part of our materials development and testing program. It is used to test slide rails made of various materials. The tester focuses on the durability and resistance of the materials and also analyzes the specific wear profiles that occur in long-term testing. The load cycle tester simulates real conveyor operation. For around 170 days, a pallet with additional weight moves back and forth on the Murtfeldt Group's slide rails made of various materials.

A laboratory press is a piece of equipment used in scientific and industrial laboratories to perform a variety of pressing operations. It plays an important role in materials research, sample preparation, and quality control. It is used to evaluate the behavior of materials under uniaxial compressive stress.

Ultrasonic measurement is a widely used method for analyzing materials. It is used to determine material thickness and to detect defects. The technique is based on the propagation of high frequency sound waves through the material. This detects cracks, inclusions, delaminations, or other discontinuities in the material. This method is non-destructive and can be used during production.

Melt mass flow rate (MFR) and melt volume flow rate (MVR) are used to characterize the flow behavior of thermoplastics. MFR stands for melt mass flow rate and used to be called melt flow index. MVR stands for melt volume flow rate and is also known as MVI, melt volume index. Both methods provide a single value that is indirectly proportional to viscosity at a relatively low shear rate.
