Mechanical testing

Tensile testing, is a fundamental materials test in which a sample is subjected to a controlled tension until failure. The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under normal forces. SCOPIC utilises a 10kN Tinius Olsen tensile testing machine and associated software capable of testing and reporting yield/tensile strength, modulus, elongation etc on a range of filled and unfilled polymers. The information obtained from such testing allows for tensile characterisation of polymer samples and analysis of the effect of functional additives.

Impact testing, utilises the kinetic energy of a falling pendulum hammer to break a test sample and to determine the energy required to do so. The resultant data gives a measure of impact toughness and can be used to report comparisons between different materials and the effect of functional additives on this property. SCOPIC can perform testing and report to both Izod (test sample clamped vertically) and Charpy (test sample rests horizontally) methods.

Any additive can affect the mechanical strength of a material, and carrying out this testing in house allows us to really put our products (and yours!) through their paces when it comes to tensile and impact strength.
