Blocking tests
The Hanatek Advanced Friction Tester is the most comprehensive tool available for measuring the coefficient of friction of plastic film, printed cartons, packaging substrates or paper.
This flexible instrument can also be used to measure and display the frictional values of any flat surface including plastics textile, coated metals and leather.
In addition to providing static and dynamic slip values for a surface, the instrument allows the full friction force output to be displayed, stored and compared. This unique ability helps a manufacturer to relate the feeding and running speeds of a product to its surface characteristics.
The instrument is available with optional extras to measure peel strength of adhesives, tear strength of substrates and the blocking of plastic films and coated cartons.
Measuring Friction
The Hanatek AFT measures both static and dynamic coefficient of friction.
Static Friction:
The initial force required to make two surfaces slip against each other.
Dynamic Friction:
The ongoing force required to maintain movement between two surfaces.
How is friction measured?
A sample of 63.5mm² with a weight acting over the entire surface area is run over another sample at a given speed.
This is typically a face to face test.
Exact test parameters are specified in ASTM D1894, ISO 8295, ISO 15359, ASTM D2534, TAPPI T549.
Features :
-
Automatic sled placement with variable dwell times give more repeatable static slip results
-
Fixed link between the sled and the load cell means that there are no errors in fricton from pulley wheels or cords associated with other measuring instruments
-
Full graphical & statistical analysis of test results can be printed to PDF for easy reporting
-
Create & store electronic references for future comparison
-
Choice of easy-load sled for measuring films or standard sled for other materials
-
Pre-loaded ISO/ASTM/TAPPI slip test methods
