The Heat Deflection Temperature (HDT), Heat Distortion Temperature, a measure a polymer's resistance alteration a load an elevated. . PVC - Polyvinyl chloride, rigid: 54: 75: PVDF - Polyvinylidene fluoride (KYNAR) 50: 125 . Factors Influence HDT .
The heat distortion temperature the temperature which piece PVC, in heat medium a bending load applied it, reaches specified deflection temperature rises. Vicat softening temperature defined the temperature the needle shaped penetrator sinks the test piece a depth.
PVC: 140: 158: 3.2: . Heat deflection temperature heat distortion temperature a to measure polymer's resistance withstanding capacity distortion a temperature. can any temperature which test bar be warped 0.35 mm a load (0.35 a random and no .
The common ASTM test determine heat deflection temperature PVC other plastic product ASTM 648. ASTM defines deflection temperature the temperature which test bar, loaded the bending stress, deflects 0.010 (0.25 mm). results obtained this test a
