  TESTS AND ANALYSIS ON PLASTICS

POLYMER IDENTIFICATION

 

POLYMER IDENTIFICATION BY MEANS OF FT-IR SPECTROSCOPY

MaterialScan  is  specialized  in chemical  characterization  of  main polymer classes (thermoplastics, thermosettings and elastomers) by means of Fourier Transform Infrared (FTIR) spectroscopy and Raman spectroscopy.

Data are elaborated by our experts in order to identify which polymers are present in the sample and to give information about crystallinity degree, thermal, chemical and environmental degradation.

Infrared spectroscopy analysis on plastics and rubber are performed in accordance with ASTM E 1252 and with UNI ISO 4650 respectively.

THERMAL ANALYSIS

 

POLYMER IDENTIFICATION BY MEANS OF FT-IR SPECTROSCOPY

 

Differential scanning calorimetry (DSC) and thermogravimetry (TGA) provide essential information on plastics.

Our laboratory is able to determine temperatures and enthalpies of fusion and crystallization, oxidative-induction time and temperature, glass transition temperature, decomposition temperature, crystallinity degree and phases (filler, blend, copolymers).

The following list reports some examples of test method performed by MaterialScan in accordance with international standard:

  • DSC on plastic materials (UNI EN ISO 11357, ASTM D3418 e ASTM E793)
  • thermogravimetric analysis (TGA) on plastic and rubber (UNI EN ISO 11358, ASTM E1131, ISO 9924 e ISO 8698)
  • oxidative-induction time and temperature (UNI EN ISO 11357-6)

THERMAL CONDUCTIVITY

 

tests on plastics and metals

 

Insulating materials play a crucial role in improving energy efficiency and thermal conductivity is the main parameter that characterizes insulating performance.

Thanks to our heat flow meter, we can guarantee reliable measurements between 0,002 and 1,0 W/m·K in the temperature range from -20°C to 90°C.

Our test methods are in accordance with the following international standard: ASTM C518, ISO 8301, UNI EN 12667, UNI EN 12664, ASTM C178.

 

To accurately measure the performance of your insulating material

 

ARTIFICIAL WEATHERING

 

 COLOUR VARIATION AFTER ARTIFICIAL WEATHERING SCANNING ELECTRON MICROSCOPE IMAGE OF A PLASTIC COMPONENT AFTER ARTIFICIAL WEATHERING

In our laboratories we carry out artificial weathering test with Xenon arc light source using both Daylight or Window glass filter.

After test completion, we evaluate aesthetic effects (i.e. surface damage) and functional properties (mechanical properties variation) induced by weathering, at the same time also photo-oxidation by-products can be identified.

  • Artificial weathering using Xenon arc lamp is accomplished in accordance with UNI EN ISO 4892, ASTM G155 (plastics) and UNI EN ISO 16474 (paints and varnishes)
  • the evaluation of coating defects after artificial weathering is compliant with UNI EN ISO 4628

MECHANICAL CHARACTERIZATION

 

THERMOSTATIC TENSILE, BENDING AND COMPRESSION TEST

 

Using a universal testing machine, we can measure the mechanical properties of plastics up to 280°C. The testing machine is equipped with a 10 kN load cell (high precision type 1/500, ±0,5%), wedge grips, compression plates, three-point bending test jig and the crosshead speed varies in the range 0,001 ÷ 1000 mm/min.

The following tests can be performed, as an example:

  • Tensile test (ASTM D638 and ISO 527)
  • Bending test (ASTM D790 and ISO 178)
  • Compression test (ASTM D695, ISO 3386 and UNI EN ISO 604)
  • Peel test (ASTM D1876)

In addition, we are able to evaluate impact resistance of plastic materials by means of a Charpy pendulum (ISO 179).

TESTS AND ANALYSIS ON METALS

METALLOGRAPHY

 

tests on metals

Mechanical properties of metals, such as steel, cast iron and non-ferrous alloys (aluminium, copper, nickel, etc.) are strongly influenced by chemical composition and microstructure.

After a specific sample preparation and polishing, MaterialScan evaluate thoroughly the effect of thermal treatment and machining on:

  • phase distribution
  • grain dimensions
  • steel microstructure (ferrite, pearlite, sorbite, troostite, bainite) lamellar or globular (after tempering)
  • martensitic structure and residual austenite
  • inhomogeneities and non-metallic inclusions

Visual examination both macroscopic (with optical microscope under low magnification) and microscopic (by means of metallographic microscope with a magnification greater than 50x) are performed in compliance with international standards.

We can employ scanning electron microscopy (SEM) combined with microanalysis EDS if a more detailed evaluation is necessary to characterize for example fracture morphology (mechanical or stress corrosion cracks, dimples) and oxidized or corroded surfaces.

MACROINDENTATION AND MICROINDENTATION HARDNESS TEST

 

METALLOGRAPHIC SAMPLE OBSERVED AT OPTICAL MICROSCOPE

 

Indentation hardness test (Brinnel, Rockwell, Vickers) can evaluate rapidly the resistance to indentation of welded joints and metal components after heat or thermochemical treatment, such as cementation and nitriding.

If it is desirable to measure the hardness of individual metallographic phase instead of component, we make available microindentation tests equipped with Knoop or Vickers indenters.

All indentation hardness test methods performed in our laboratory are compliant with the main UNI and ASTM standards.

CORROSION RESISTANCE OF ALUMINIUM ALLOYS

 

We perform test to evaluate the behaviour of aluminium alloys exposed to particularly severe conditions able to induce material corrosion (intergranular corrosion in the case of 5XXX series) or exfoliation (for series from 2XXX to 7XXX).

Tests are in accordance with standard ASTM G34, ASTM G66 and ASTM G67.

 

X-RAY DIFFRACTOMETRY (XRD)

X-ray diffractometry (XRD) is a non-destructive technique that allows the identification of phases present in a sample based on the diffraction peaks typical of each material.

The technique can be employed to different classes of materials such as metals, advanced ceramics and plastics, for example to identify fillers (carbonates, sulphates, silicates, etc.).
