Overview
Deepak HDT/VSP instrument is used for determining the deflection temperature limit for specific application and comparing the heat softening characteristics of thermoplastic material at a constant load in oil media up to
300º C.
Plastic materials, being heat sensitive in nature, have a lot of bearing on thermal environment for their performance. Though their behaviour in thermal conditions is very complex, some simple yield tests are used to predict its behaviour and performance in a given condition. 'Vicat Softening Point' or 'Heat Deflection Temperature' is one of such yield points, very commonly used for engineering plastics. Vicat test consist of penetrating a unit size indenter in a plastic surface with predefined load under constant rate of environmental temperature rise.
Heat distortion test, as it is sometimes called, consists of deflecting a simply supported beam of test material under similar heating conditions and with a predefined stress application.
Available range of VSP Tester – Single Station, Two Stations, Three Stations, Four Stations & Eight Stations.
