Dynamic mechanical properties of an ultra high molecular weight polyethylene reference material SRM 8456

The dynamic mechanical analysis storage and loss modulus of a NIST SRM 8456 Ultra High Molecular Weight Polyethylene is determined in 3-point bending in an interlaboratory test. Mean values of (1.18?±?0.17)?GPa for storage modulus and (62.0?±?9.0)?MPa for loss modulus were determined at 21?°C. In addition, the temperature (molecular) spectrum for the material is observed between ?100 and +100?°C. These results permit the use of this material for calibration, conformance, and performance demonstration for dynamic mechanical analyzers.
