Melt Flow Index (MFI), also known as Melt Flow Rate (MFR) and Melt Index (MI), is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary at a prescribed temperature by a pressure applied.
Melt flow rate is an indirect measure of molecular weight, with high melt flow rate corresponding to low molecular weight. At the same time, melt flow rate is a measure of the ability of the material's melt to flow under pressure. Melt flow rate is inversely proportional to viscosity of the melt at the conditions of the test.
The test method is described in ISO 1133 and is similar to ASTM D1238.

Melt Volume Rate (MVR) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the volume of polymer, in cm³, flowing in ten minutes through a capillary at a prescribed temperature by a pressure applied.
Melt volume rate is an indirect measure of molecular weight, with high melt volume rate corresponding to low molecular weight.

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.

In order to perform tests such as tensile, impact and bending tests, a sample of the polymer has to be prepared in the dimensions required for these tests. This is done by injection molding and the shape (often referred to as dumbbell or dogbone) and dimensions of the sample are described as ISO 3167 type A (also known as ISO 527 type 1A).
Please contact us for more information.
Make sure to include information on the chemical nature (e.g. PP, PE, PET, PA,... preferably with a safety datasheet) of your polymer with your order.

In a tensile test, the force and associated sample elongation are measured until the sample breaks. From this data the following parameters can be determined: tensile stress (at yield & at break), strain, elongation (at yield & at break), modulus.
The test method is described in ISO 527.
The dimensions of the provided samples should be according to the specimen dimensions specified in the standard.

The three point flexural/bending test (incl. flexural modulus ) is used to investigate the flexural behaviour of the test specimens and to determine the flexural strength, flexural modulus, bending and other aspects of the flexural stress/strain relationship under the conditions defined. The configuration used is a three-point loading test where the specimen is freely supported at both ends and a varying load is applied at midspan during which the bending/deflection deformation is measured.
The test method is described in ISO 178.
The dimensions of the provided samples should be according to the specimen dimensions specified in the standard.

Vicat Softening Temperature (VST) is the temperature at which a polymer starts to “soften” under a load, more specifically when a needle reaches a set indentation/penetration depth. 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 306 and is similar to ASTM D1525.
