plastics heat deflection temperature (HDT) value Complete Guide
heat deflection temperature (HDT): (HeatDistortion Temperature,HDT)
heat deflection temperature (HDT) plastics material in high temperature pressure lower can maintain outer 形, generally use table/sheet plastics short heat resistant property. short use most high temperature degree maintain low heat deflection temperature (HDT) 10℃ left right, ensure 不至于因 temperature degree make material deformation. most commonly used hot deformation method is ASTM D648 experiment/testing method, will sheet/slice in pressure and processing temperature speed degree lower, bending to 一定程 degree temperature degree.
