In modern material manufacturing, surface sliding performance is a critical indicator affecting production efficiency and product safety. The Coefficient of Friction Tester, commonly known as COF Tester, is the standard laboratory instrument used to measure static friction coefficient and kinetic friction coefficient of flat and flexible materials.
Many manufacturers rely on manual experience to judge material smoothness, which leads to inconsistent evaluation results. COF testing turns subjective feeling into quantifiable data.
If the COF value is too high: films or sheets will jam during high-speed automatic feeding, causing breakage and production downtime. If the COF value is too low: materials may shift, slide or collapse during stacking, packaging and transportation, bringing hidden risks.
Standard Compliance & Technical Highlights
Our COF Tester is designed in accordance with international standards ASTM D1894 and ISO 8295.
Equipped with high-precision force sensor and stable driving structure, it records real-time force change curves throughout the test. The equipment automatically calculates static COF and kinetic COF, supports data storage, analysis and test report output. The touchscreen interface enables easy parameter setting including test speed and travel distance.
Wide Range of Applications
Applicable Materials:
Plastic films, composite packaging films, aluminum foil, paper, cardboard, non-woven fabrics, rubber sheets, lithium battery separators and coated panels.
Target Industries:
Flexible packaging enterprises, plastic film manufacturers, printing factories, new energy material suppliers, medical material laboratories and third-party testing laboratories.
Stable and repeatable test data helps enterprises optimise raw material formulations, standardise incoming material inspection and control finished product quality. Custom fixtures and optional accessories can be configured to meet special sample testing demands.
For factories aiming to realise standardized quality control, COF testing has become an indispensable routine testing item. Feel free to contact us to learn more about testing principles, operation methods and equipment parameters.
