Aluminium foil flex failure tester Metalized film flex durability tester measures the resistance against repetitive strain for films, composites and coating films, etc. Flex failure property is determined by measuring the pinholes formed in the sample structure. Flex durability tester is also called Gelboflex.
Aluminium foil flex failure tester Metalized film flex durability tester Principle
The sample size (200 by 280 mm) is attached to the flex tester mandrels. The flexing action consists of a twisting motion combined with a horizontal motion (compression), thus repeatedly twisting and crushing the film. The test set up gives a twisting motion of 440º in the first 90 mm of the stroke and is followed by a straight horizontal motion of 65 mm. The speed is 45 cycles per minute.
