Why Use Polymer Testing Services from ExcelPlas?
Our polymer material testing services help you to:
• Identify the characteristics, properties and flaws of your materials
• Comply with all relevant national and international standards(ISO,ASTM,..)
• Ensure that your polymeric materials meet your clients’ safety, environmental and  requirements

Composition of a plastic material
By combining different analysis techniques, we can obtain the composition of an unknown plastic material or compound, thus identifying which polymer or polymers, mineral fillers and reinforcements are present. Likewise, the percentage of these mineral fillers.  This information is very useful to ensure compliance with the requirements needed to obtain the technical data sheet of a material, to understand the possible causes of failure in manufacturing or service, etc.

Verification of specifications for poly pipes and their raw materials
With extensive experience in testing for the plastic pipe industry (PE, PP, PVC, PEX, GRP pipe..)
In this regard, we perform carbon black content tests, carbon black dispersion tests, Oxidation Induction Time (OIT), Tensile, Vicat, among others, all aimed at ensuring minimum values that enables compliance with the required technical specifications.
In addition, we determine the degree of cross-linking and the gel content in PE-X pipes, as well as in any other cross-linked materials.
Some of our testing capabilities include:
• Thermal Anaylsis (DSC, TGA, ASH content)
• FTIR
• XRF
• XRD
• SEM,TEM,AFM
• HDT-VICAT Test Instrument
• UL94 Flammabilitty
• Rheometry (Melt Flow Inedex, Capillary Rheometer)
• Universal Testing Machines
• Shore A&D
• Density
• ESCR
• Twin screw extruder for R&D activity
• Hydrostatic test for plastic pipe

FAILURE ANALYSIS

HDPE PIPE JOINT FAILURE EXPERTS
The failure of electrofusion or butt fusion joints in polyethylene gas pipework can be due to several factors including incorrect alignment, contamination, incorrect temperature or the duration of joint fusion. 
If a joint failure occurs, investigations are important to help identify modifications to procedures or training that can help you minimise the occurrence of future failure. This is where we can help.
We provide a detailed PE joint failure investigation service which typically include:
• Digital inspection of the received sample, including dimension measurements of sizes and ovality
• Segmenting the joint for visual and microscopic investigation
• Elemental analysis of any contamination found in the joint
• Peel decohesion testing

ExcelPlas Labs Pipe Failure Investigations
ExcelPlas Labs have created a new benchmark in failure analysis of HDPE, PP-R, PB and PEX pipes in addition to PVC &  CPVC pipes as well as composite GRP and GRE pipes.  When a plastic pipeline fails to perform as intended, our team can determine the root cause of failure (e.g.  oxidative failure, chemical failure, creep failure, over-stress failure, fatigue failure, design failure, etc).  ExcelPlas are experienced with all plastic piping failure modes and mechanisms including Slow Crack Growth (SCG) Rapid Crack Propagation (RCP), Environmental Stress Crack Resistance (ESCR), Oxidative Stress Cracking (OSC), cyclic fatigue, manufacturing defects, and polymer material problems.

ExcelPlas Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason.  The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.

ExcelPlas Poly Pipe Weld Inspection Lists Top 7 Causes of Weld Failure:

  • Lack of scraping
  • Inaccurate scraping
  • Contamination from dirt, water, oil or clays
  • Lack of Paralell-ness of fusion faces
  • Misalignment of surfaces
  • Time, temperature and pressure deviations
  • Not adhering to cool times

We have extensive experience in inspection of poly pipe welds for assuring welded joint quality.  Direct Poly Pipe Inspection ensures that operators are following the proven welding procedure; this reduces the occurrences of operational errors which lead to defects such as inclusions, lack of fusion (LoF), porosity and misalignment.
