Heat Distortion Temperature The short term thermal performance of a material may be characterized by determining the Heat Distortion Temperature (HDT, ASTM D 648). 0 100 200 300 400 500 600 Heat Distortion Temperature (°C) A comparative chart of high performance material using ASTM D 648, HDT values (Fig. 1) for a defined applied stress of 1.8 MPa TM shows that GAZOLE 5200 grade is superior to all of the other polymeric wear grade composites. 3. Abrasion Resistance The ability of a material to withstand mechanical action such as rubbing, scraping or erosion, that tends progressively to remove from its surface.
