This sample pack includes a 6x6" sample of Acetal, Nylon, UHMW, a 4x4" sample of Tivar HPV and a 3x3" sample of PTFE.
The Friction Resistance Sample Pack features plastics with a low coefficient of friction. It is vitally important to test which -slippery" plastic is going to work for your specific application, as friction related problems lead to electronic and machinery damage, as well as complete equipment failure.
Dynamic (also known as kinetic) friction occurs when two objects are moving relative to each other and rub together. The amount of friction resistance a material has is measured as a coefficient; the closer to 0 the coefficient, the less dynamic friction is exhibits.
The correct amount of friction resistance for your project will vary based on many factors (temperature, humidity, interacting materials, etc.), and there is no material that will outperform any other for all applications.
