HDT – heat deflection temperature

Briefly about material properties:

TENSILE STRENGTH is a mechanical property of a material defined as the maximum amount of tensile stress that a bar made of such material can take before failure, for example breaking. Tensile strength is important for all materials which will elongate or will be placed under tensile stress. The tensile strength of many brittle materials, such as rock or concrete, is practically negligible.

TENSILE MODULUS (E), also known as the Young modulus, is defined as the proportionate coefficient between the force per a unit of cross-section and the relative elongation of the object. Stiff materials, e.g. metals, have a high tensile modulus, while the tensile modulus of elastomers is low. Plastic materials show mid-range values.

ELONGATION AT BREAK is the percentage increase in length that a material will achieve before breaking. The value is very low in brittle materials, and high in elastic materials.

HEAT DEFLECTION TEMPERATURE is the temperature at which a polymer or plastic specimen deforms under a specific load. The test specimen is placed on a support and loaded in the middle with a load of 0.45 MPa or 1.8 MPa. The specimens are then dipped into an oil bath where the temperature is increased at 2 °C/min until the specimen deflects 0.32 mm or 0.34 mm (ISO 75).
