Coefficient of Friction Tester

Product Introduction

The Friction Coefficient Tester is a dedicated measuring instrument for determining the dynamic and static friction coefficients of plastic films, sheets, paper, paperboard or other items by the plane sliding method. By simulating the relative sliding process of materials under specific conditions, it quantifies the surface friction characteristics, providing key data support for product quality control, process optimization and research and development.

Application Scope

It covers multiple core industries that need to control surface friction performance: the packaging industry (core application) is suitable for films, paper, aluminum foil and composite films, testing opening property and slipperiness to ensure smooth production and packaging; the rubber and plastics industry can evaluate the friction performance of products such as tires, sealing rings and conveyor belts; the medical and daily chemical industry can determine the surface friction or slipperiness characteristics of medical catheters, gloves, cosmetics and eye drops; the textile industry is used to test the slipperiness of fabrics and the friction performance of accessories such as zippers and hook-and-loop fasteners.

Working Principle

The test samples are respectively fixed on the horizontal test table and the slider. Under a certain contact pressure (normal force), the driving mechanism drives the slider or the test table to move, that is, the surfaces of the test samples make relative motion. The magnitude of the friction force is measured by a force sensor and compared with the normal force to calculate the friction coefficient of the test sample.
