In the plastic film industry, it is important for you to determine the stackability of these films to produce accurate products for the customers. Thus, testing the friction of these plastic films is of utmost importance to prevent accidents from occurring during transportation and shipping. To ease the work of testing co-efficient of friction for plastic films, we at Testronix Testing Instruments have come up with one of the amazing testing instruments known as co-efficient of friction testerThis lab testing equipment is used to determine how easily the two surfaces of the material will slide over each other. If the friction value of these surfaces will be low then it will simply mean that the surface will be slicker, which means that it is less resistant to sliding motion. Thus, you will be able to determine the slip properties of these materials with ease.

Here in this blog, we are going to provide you the information about the Testronix co-efficient of friction tester and how this lab testing equipment is helpful in determining the quality of plastic films delivered to the customers. So, let us get started!

What is the coefficient of friction and how it is determined by the Testronix COF tester?

By pushing or sliding the facades of two materials against one other, the coefficient of friction, also known as COF, may be easily be determined. The ratio of the force required to slide the material façade to the force acting perpendicular to the surfaces is the dimensional value of the coefficient of friction. A lower co-efficient friction value indicates that the surfaces are slicker, implying that the material is less resistive to sliding action.

The friction of a sheet of paper, plastic film, or paperboard is measured with a Testronix coefficient-of-friction (COF) tester. It aids in determining the angle at which the adhered substrate begins to slide or slip across the surface of another substrate of the same or different material.

This friction testing instrument is highly useful to determine the friction quality of a particular plastic film and determine the amount of frictional force delivered when these plastic films are dragged against each other. Its test value will be recorded digitally on the digital screen display which is based on a microprocessor-based program. This lab testing equipment is used as per industrial standards like ASTM D 618, ASTM D 883, BS 2782, and ASTM D 1894.

Now, let us discuss the features and technical specifications of this testing instrument. 

Features of Testronix co-efficient of friction tester

One of the most often requested features in packing films is a controlled amount of friction. Lack of friction can cause packets to slide from one another during storage or travel, disrupting the contents within and perhaps resulting in packing failures. Bursting of the film and leaking of the product if in liquid form or shattering of the substance packed inside are examples of failures.

There are two types of friction: static friction and kinetic friction. The plastic film's static friction prevents it from moving while it is standing still, and its kinetic friction prevents it from slipping away while it is moving. Thus, with the help of the Testronix static and dynamic friction tester, it will be easy for you to test the frictional properties of these materials. Here we have listed the features you will get with the help of this testing instrument.
