A coefficient-of-friction tester for plastic films, flexible packaging, paper, board and laminates — offered as a horizontal-sled model to ASTM D1894 (Static & Kinetic Friction Tester) and an inclined-plane model to TAPPI T-815. Covers film-to-film, film-to-metal and film-to-glass friction for every common COF requirement.
Coefficient of friction (COF) is one of the most important surface properties of any plastic film, packaging laminate or paper product. Too high a COF causes packaging machines to jam, films to drag on conveyors and bottles to stick on bottling lines. Too low a COF makes film rolls slip, pallets lose stack stability and surfaces become a safety hazard. COF is controlled by slip and anti-block additives and must be checked batch to batch.
International Equipments builds two COF instruments: a horizontal-sled Static & Kinetic Friction Tester to ASTM D1894, and an Inclined Plane Tester to TAPPI T-815. The computerised sled model adds PC Load-vs-Travel graphing and 10-sample statistics with mean and standard deviation. Manufactured in Mumbai, CE marked and calibration-certified.
Choose the model that suits your standard and sample type.
Horizontal-sled method: capacity up to 9.999 kg, test speed 150 mm/min, 200 g sled and three SS templates, with direct readout of Static and Kinetic COF. The computerised variant replaces the digital controller with a microcontroller + RS232 and ships with Windows interface software for live Load-vs-Travel graphing, result storage and printout, and statistical merging of up to 10 samples (mean + SD) in a single report.
Tilting-plane slide-angle method at 1.5°–2.0° per second with a 750 g, 4″×2″ sled and two SS templates. Measures Static COF only (no sliding phase) and is the standard COF method for paper, paperboard, corrugated packaging and tissue — covering film-to-film, film-to-metal and film-to-glass combinations.
