Name: QM110CF
Brand: Br&Qmesys

QM110CF Coefficient of Friction Tester

The QM110CF tests static/dynamic COF of film, paper and plastic surfaces, dragging a standard sled at a constant servo speed to measure friction force; it is a quality-control instrument for the surface slip properties of packaging and functional films.

High-precision constant-speed servo drag ensures static and dynamic friction are measured and output separately in one test; dual standard loads of 3 and 6 kgf cover soft films to hard sheets, with excellent measurement repeatability.

Wide speed range 0.1~600 mm/min, stroke up to 150 mm, optional RT~220°C heating to simulate service conditions; suited to ASTM D1894 / ISO 8295 surface-friction evaluation of packaging and composite films.

Key Product Features

Coefficient of friction - authoritative research confirms the key role of COF testing in evaluating material surfaces.

Constant-Speed Servo Drag

A high-precision servo motor drives the sled across the surface at constant speed; friction force is acquired in real time, with excellent repeatability for static/dynamic COF.

Separate Static/Dynamic Measurement

One test records both the initial static friction force and the stable sliding dynamic friction force, automatically outputting static and dynamic COF.

3/6 kgf Dual-Load Sled

Two standard-load sleds are supplied; per ASTM D1894 / ISO 8295 they match the different counterface requirements of soft films to hard sheets.

Wide Speed Range 0.1~600 mm/min

Sled speed is continuously adjustable, covering standard slow tests and fast scans; stroke up to 150 mm suits long specimens.

Quick-Release Fixture + Optional Heating

A one-hand pin-type detachable fixture holds soft films without slip; an optional heating platen RT~220°C simulates high-temperature service conditions.

Films and Plastics
Static/Dynamic COF Testing

The QM110CF COF tester drags a sled (standard slider) of specified load across the surface, automatically measuring the initial friction force (static COF) and the friction force during motion (dynamic COF). With a high-precision servo system, stroke up to 150 mm, speed range 0.1~600 mm/min, a Japanese Original Rubber pad as standard and optional heating up to 220°C.

From packaging films to lithium-battery separators: the surface coefficient of friction directly affects packaging open/close force and processability. Static COF determines whether materials slide easily; dynamic COF determines friction stability during processing; both are core indicators for evaluating film and plastic surfaces.

Designed for film friction evaluation: sled drag plus constant-speed servo, compliant with the ASTM D1894 friction standard.

FAQ

Answers to frequently asked questions about purchasing, delivery and service for the QM110CF COF tester.

What is the QM110CF COF tester mainly used for? +

It tests static and dynamic COF of films, paper, plastic sheets and soft surfaces. Under a specified load it drags a standard sled, automatically measuring the initial static friction and the moving dynamic friction, to evaluate surface slip, openability and runability; suited to R&D and line quality control of packaging films, composite films and coated films.

What are the key technical parameters of the QM110CF? +

See the specification table: capacity (load) 3, 6 kgf, stroke range Max. 150mm, speed range 0.1~600mm/min, optional heating RT~220°C, overall dimensions 540×400×390 mm.

How are static and dynamic friction measured? +

A high-precision servo motor drives the sled across the surface at constant speed, acquiring the friction-force curve in real time: the maximum force at the instant the specimen moves from rest is the static coefficient of friction, and the force during stable constant-speed sliding is the dynamic coefficient of friction; both are output in one test.

Is heating supported? +

Yes. An optional dedicated heating platen is available, with a temperature range of RT ~ 220°C to simulate how film friction changes under high-temperature service, laminating or storage conditions.

Which test standards are supported? +

Applicable standards are listed in the specification table and product manual, covering ASTM D 1894 (static/dynamic COF of plastic film and sheeting), ASTM D 4917 (paper COF), ISO 8295 (COF of plastic film and sheeting), KS M 7134 (plastic film COF).
