Heat distortion temperature (HDT)
Heat deflection temperature (HDT) is the temperature at which a polymer starts to “soften” under a load, more specifically when the specimen reaches a set deformation in a bending configuration. It refers to a polymer's ability to remain rigid or “stiff” under a constant load and elevated temperatures.
The test method is described in ISO 75 and is similar to ASTM D648.
The dimensions of the provided samples should be according to the specimen dimensions specified in the standard.
Test specimen can also be prepared at an extra cost, contact us for more information.
Please include information on the chemical nature (e.g. PP, PE, PET, PA,..) of your polymer with your order.
