WebHeat deflection temperature is used to determine short-term heat resistance and is equivalent to the temperature at which a standard test bar deflects a specified distance under a load. It distinguishes between materials that are able to sustain light loads at high temperatures and those that lose their rigidity over a narrow temperature range. WebAcrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). ABS is amorphous and therefore has no true melting point.. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.
