-TGA Thermogravimetric Analysis for weight loss with loss of additives, oils, polymer decomposition, filler levels
-X-Ray Analysis (EDS/XRD) to identify the crystalline phase and composition of inorganic additives
-Carbon Black Content (ASTM D1603, AS/NZS 2904 Clause 7.4.5 which uses AS 1463 Appendix B)
-Carbon Black Dispersion
-Oxidative Induction Time (OIT)
-Melt Flow Index (MFR)
-Stress Cracking Resistance Testing (ESCR testing)
-Failure Analysis (processing, water treeing, contamination ID, etc)

Examples of Polymer Materials Excelplas Can Test:
XLPE and HDPE Cable Insulation Testing (QA, QC, incoming raw materials)
* PVC (V-90) (Soft (plasticised) Polyvinyl Chloride compound)
* XLPE (X-90, X-HF-110) (Crosslinked Polyethylene)
* Rubber (R-EP-90, R-HF-90, R-HF-110) (Ethylene Propylene Rubber).

ExcelPlas Undertakes the Following Cable Testing as per AS/NZS 5000 and AS/NZS 3808:
* Measurement of thickness of insulation and sheath (sample test)
* Tensile strength and elongation of insulation and sheath material – before ageing (type test)
