Plastic Medical Packages

Measuring friction can be important factor for many industries, especially for plastics and packaging. Friction can be characterized by static friction, and kinetic friction. Static friction of plastic is present when two objects are in contact but not sliding across each other. Kinetic friction is a resistance friction that is present during sliding motion between two objects. The coefficient of friction is dependent on the surface conditions of both materials that are in contact. Testing standards such as ASTM D1894 and ISO 8295 cover the testing methods to determine the coefficient of plastic materials. Testing involves pulling a weight with a plastic specimen between the weight and the ground. The force required to do so can be measured and a coefficient of friction is then determined. TestResources plastic coefficient of friction test equipment is modular and configured by our applications engineer to match your specific material, sample type and test method. Our product line includes a wide variety of test machines, test software, grips, test fixtures, extensometers, sample preparation aids, and environmental chambers.
