Gelboflex tester is used to measure the resistance against
repetitive strain for films, composites and coating films, etc.
Flex failure is determined by measuring the pinholes formed in the
sample structure. It is also called flex durability.
Gelboflex tester working 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.
