Mechanical Properties Testing

The term mechanical properties are commonly used to denote stress-strain relationships for polymer systems. It involves the behavior of the polymer under the application of stress and include the extent of stretching, bending, hardness, etc. Mechanical properties testing of polymers is a key part of the product development design and production process. It helps developers to evaluate the behavior of polymers in greater depth. Alfa Chemistry offers mechanical property testing services to ensure that your polymer products meet specifications and comply with the required regulations and quality standards.

Our test projects

The testing of mechanical properties of polymers is of primary and fundamental importance in determining their applicability in any technical field. Our test projects include, but are not limited to the following.

● Tensile testing

Tensile testing is essential for the characterization of the polymer materials’ behaviors. It is performed by applying a continuously increasing tensile force to the major axis of the sample until it breaks. Tensile testing provides customers with parameters such as tensile strength (at yield and at break), tensile modulus, tensile strain, yield point, yield strength and percentage elongation at breaking point.

● Compression testing

ompression testing

The compression test helps to determine the behavior of a polymer material under compressive forces. It can determine the modulus of elasticity, proportional limit, compressive yield point, compressive yield strength, and compressive strength, in addition to the force-deformation curve of the polymer material. It is one of the common testing methods in many industries, including automotive, furniture, electronics, and construction.

● Impact testing

Impact testing has become an important technique to determine the parameters associated with dynamic fracture of polymeric materials. These parameters are commonly calculated from the experimentally measured load versus time curves. We offer Izod and Charpy testing to determine the impact properties of polymer materials.

● Flexural testing

Flexural testing

The flexure test measures the mechanical properties of polymer materials when subjected to bending load. It can determine several important mechanical properties, including the flexural modulus, yield stress and breaking stress. Flexure tests can be accomplished by three-point bending or four-point bending. For plastics with small extensibility and large extensibility, the most common method is the three-point bending method with different span lengths.

● Shear testing

Shear testing is performed to understand the behavior of the polymer material under shear loading. The most common parameter obtained from shear tests is the shear strength, which is the maximum load a polymer material can withstand in a direction parallel to the surface of the material, rather than perpendicular to its surface.

Shear testing

Our test standards

Our test standards mainly include ASTM D638, ISO 527, ASTM D695-15, ISO 844, ASTM D256, ASTM D4812, ASTM D6110, ASTM D790-03, ISO 178 and ASTM D3846.
