Hardness of Plastics and Rubbers

Hardness is defined as a material’s resistance to permanent indentation. It is one of the most measured parameters and often reported on technical data sheets of plastics and rubbers.

Impact test on plastic films

Determination of the energy that causes plastic film to fail under specified conditions of impact of a free-falling dart. This energy is expressed in terms of the weight (mass) of the missile falling from a specified height which would result in 50 % failure of specimens tested.

Charpy & Izod Impact tests

There are two types of test use for testing the Impact resistance of any material one is Izod Impact resistance test and other is Charpy Impact resistance test. Both of them use the same principle to test the Impact resistance of any material but still there are may difference in them and our today's article will show these difference between Izod and Charpy Impact testing

Universal tester

The universal tester is used to determine the tensile stress diagram, the bending modulus and compression force of plastic samples


DSC is a thermal analysis technique which couples temperature and heat shift to material transitions, in function of time and temperature in a controlled environment.


TGA is an analytical method that measures the changes in weight of a test sample during a heating process.


Analytical method to determine the thermo-mechanical properties, under a dynamic load, of a plastic during heating and cooling.

Rotational rheometry

Rotational rheometry is a powerful technique for the measurement of complex shear rheology across all material types – sensitive enough to measure the viscosity of dilute polymer solutions, and yet robust enough to measure the viscoelasticity of high modulus polymers or composites

Capillary rheometry

Capillary rheometers principle is based on measurement of the melt flow, by a pressure applied through the precisely dimensioned capillary.


The Rheotens® technology has proven its efficiency to provide very reproducible and accurate measurements. It is also possible to determine slight differences in molecular structure which cannot be found by other methods.
