Co-efficient of Friction Tester (Dynamic Model)
This method covers determination of the coefficient of starting and sliding friction of plastic film and sheeting when sliding over itself or other substance at specified test conditionThe Co-efficient of friction reveals the stack ability of plastic films. Helps prevent accidents due to friction in packaging; loading; transportation of materials. Friction could result from uneven film thickness; which leads to uneven film strength. Co-efficient of friction also tells you the degree of abuse a plastic film will sustain without damaging the contents.
Measure the co-efficient of sliding friction. Simple but precise instruments. Designed to determine the co-efficient of friction of plastic film. By checking the friction that exists between 2 surfaces covered by the same plastic material.
Slip properties are generated by additives in some plastic films, for example, polyethylene. These additives have varying degrees of compatibility with the film matrix. Some of them bloom, or exude to the surface, lubricating it and making it more slippery. Because this blooming action may not always be uniform on all areas of the film surface values form these tests may be limited in reproducibility.
