COF-01 Coefficient of Friction Tester Background The coefficient of friction pertains to the friction present between two surfaces. A lower coefficient of friction signifies that less force is needed for sliding to commence, while a higher value indicates a greater force requirement. The coefficient of friction varies based on the specific materials involved. In the context of packaging film, the coefficient of friction refers to the extent of 'slipperiness' exhibited by the packaging material when in contact with different components of the packaging machine or other materials. The management of the coefficient of friction holds significance in enhancing performance and mitigating issues during the creation, transportation, and storage of packages. Numerous factors, such as antiblock additives, corona treatment, antistatic agents, inks, varnishes, and adhesives, can influence the coefficient of friction. Application The COF-01 Coefficient of Friction Tester is designed to measure both static and kinetic coefficients of friction for a wide range of materials. These materials include plastic films, sheets, rubber, paper, paperboard, woven and non-woven fabrics, metal-plastic composite belts used in communication cables and conveyor belts, wood, coatings, brake pads, windshield wipers, shoe materials, and tires.

Background Given the extensive applications of mop materials in diverse settings, including homes, offices, and industries, rigorous quality testing is essential. While their ease of washing and high absorbency are valuable traits, consistent performance over time is vital. Quality testing ensures mops retain their absorbency and durability, upholding their effectiveness in tasks such as cleaning kitchen surfaces, windows, and furniture. This process identifies and addresses potential issues, maintaining the reliability and functionality of mops across various uses. Application COF-S1 is a specialized coefficient of friction tester for mop and cleaning materials like microfiber mop pads, sponge mops with foam blocks (cellulosic, rubber, or plastic). Friction varies based on usage for liquids, dust, and dry surfaces. The mop's friction coefficient affects its cleaning efficiency and usability. Excessive friction raises labor intensity, while too little hampers cleaning, thus requiring a balanced coefficient for optimal performance. Formula COF is determined by dividing the force needed to move one surface across another by the force perpendicular to the surfaces. It has two kinds: Static and Kinetic. Static COF �µs is measure of force required to begin movement. Kinetic COF �µd is measure of force required to maintain movement. Test Method Fix the sample cloth to its aluminum or plastic frame, then the total assembled part is placed under a certain weight. The block, together with the sample and its frame, is pulled at a speed of 500mm/min, for 500mm distance. The static and kinetic coefficient of friction are recorded.
