The Vicat softening temperature is the temperature at which the needle has penetrated the polymer to a depth of 1 mm. For such a depth of penetration, the material must be very soft, hence the Vicat softening temperature is higher than other HDT data. [Pg.914]
WebSPOLIATION OF EVIDENCE From the Georgia Bar Journal By Lee Wallace The Wallace Law Firm, L.L.C. 2170 Defoor Hills Rd. Atlanta, Georgia 30318 404-814-0465 WebThe Vicat point is closer to the actual melting or softening point of the polymer, the Vicat number will typically be higher. Heat Deflection Temperature Vs Glass Transition Temperature (Tg) As discussed above, HDT gives an indication of how the material behaves when stressed at elevated temperatures. A material can have only “one” HDT.
