GM-4 Coefficient of Friction Tester
Product Overview
The GM-4 Coefficient of Friction Tester quantifies both static and kinetic friction coefficients for diverse substrates including plastic films, multi-layer composite films, aluminum foils, metallized films, rigid sheets, rubber and ceramics. The measured friction data enables precise assessment of film slip properties, opening behavior and material homogeneity, delivering reliable reference data to fine-tune production parameters.
