The Presto Co-efficient of Friction Tester is built on a rigid metallic base plate. The instrument is finished in Autumn Gray & Blue combination painting and bright chrome / zinc plating to give it a corrosion resistant finish.
It comes complete with an Instruction Manual; the Electrical Wiring Diagram & also a Calibration Certificate traceable to NABL approved Labs.
It measures the static and kinetic friction of the test sample, when it slides over itself or other substances in a specified test condition.
The co-efficient of friction studies are essential in evaluating the stackability of plastic films and sheets. These studies enable plastic manufacturers to prevent accidents due to friction in packaging, loading and transporting materials. Uneven film thickness could result in increased friction, which in turn leads to uneven film strength.
Co-efficient of friction studies also reveal the degree of abuse a plastic film will successfully endure, without damaging the contents. The Presto Co-efficient of Friction Tester accurately measures the co-efficient of sliding friction.
It is a simple yet precise instrument, specially designed to check the friction that exists between two surfaces covered by the same plastic material. In some plastic films, like polyethylene, slip properties are generated by additives.
These additives have varying degrees of compatibility with the film matrix. It is a well known fact that sometimes the samples bloom or exude to the surface, thus, lubricating it and making it more slippery. Since blooming may not be uniform on all areas of the film surface, the results generated from these tests may not be reproducible.
The frictional properties of plastic film and sheets may be dependent on the uniformity of the rate of motion between the two surfaces. The data obtained by these procedures may be extremely sensitive to the age of the film or sheet and the condition of the surface.
Slippage is an important quality factor of quality flexible packing. I never thought, stacking friction is important. Thanks to the expert team of Presto for making me aware about it and the product is really amazing.— Prashant Dubey
