Measure Impact Strength Of Plastics With Dart Impact Tester

Impact strength is the involuntary property of polymers. As a molecular elasticity, it plays a major role in evaluating the relative stiffness of materials. The stiffness of a material is explained as the capability of the polymer to absorb applied force. Usually, plastic films are used for packing purpose which can undergo various stages of wear and tear. Hence, Strength of the impact resistance of plastic film is recognized to conclude the quality and to make the film withstand the impact load. This test method includes all the determinate of the force that can damage the plastic under some determined conditions when come in contact with the free falling dart. The force is expressed in terms of weight of mass directly falling from a determined height which can result in 50 percent failure of the sample. 

Presto Stantest provides an extensive range of impact testers for different plastics, sheets, films, decorative laminates, roofing sheets with the wide range of weight of darts along with the facility of setting different height of fall with less effort. The Presto’s dart impact tester comprises of an electromagnetic release mechanism that helps to set light and heavy weight dart. Weights ranging from 5 grams to 500 grams are supplied with the machine. Also the height of the dart can be set as per the requirement at 220mm, 660mm and 1524mm. Moreover, a high tech vacuum pump is also provided with the testing equipment as an optional accessory and clamping system is provided to tightly clamp the film on the instrument for reliable and accurate results. Also, the instrument comprises of a digital counter to view the highly precise results in digital format.
