High Heat Resistant ABS Technology

RONY VANSPEYBROECK, ROBERT P. DION, AND JOSEPH M. CERASO 

The heat resistance performance of a resin is the temperature at which a part will start to be dimensionally unstable and to distort under load. There are various laboratory tests to predict this performance. 

The most commonly used are the measurement of the Vicat softening point (ASTM D1525, DIN 53460, ISO 306) and the deflection temperature under load (DTUL, ASTM D648). Both measurements monitor the modulus change with temperature, and determine an endpoint when a macroscopic change can

The heat performance of conventional ABS correlates in general with the glass transition temperature (Tg) of the rigid phase. Table 15.2 lists some typical rgs of amorphous polymers. Also listed are the crystalline melting points (Tm) for semi-crystalline polymers. Typically, the heat performance of a neat semicrystalline polymer under low load correlates with its Tm.
