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

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

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

DTMA

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

Heat Deflection temperature

The heat deflection temperature or heat distortion temperature is the temperature at which a polymer or plastic sample deforms under a specified load.

Vicat Softening Temperature

The Vicat softening temperature is the temperature at which a flat-ended needle penetrates the specimen to the depth of 1 mm under a specific load.

MFR

The Melt Flow Rate measures the ease of flow of melted plastic and represents a typical index for Quality Control of thermoplastics.
