Plastics are synthetic or semi synthetic viscoelastic materials composed of organic polymers and organic or synthetic additives. The behavior of plastics under stress depends on the length of time they are exposed to the stress and the temperature the exposure occurs.
Plastic Material Testing Goal:
Testing a plastic’s mechanical properties determines if it will meet the requirements of the desired application. Desired characteristics of plastic products are low cost, low weight, high toughness, high elasticity and ductility, and high strength in tension, compression, flexure, torsion and shear.
Common Plastic Test Methods:
The most common tests of plastics are tensile tests, compressive tests, flexure tests, shear tests and torsion tests.All of these tests are run until the sample breaks or ruptures with the stress and strain values recorded throughout the duration.
