Film torsion and flexing Gelbo endurance tester ASTM F392 Gelbo flex tester

Film torsion and flexing Gelbo endurance tester ASTM F392 is an ideal sampling machine for the repetitive strain for films, composites and coating films, etc.

Flex failure is determined by measuring the pinholes formed in the sample structure and change in permeability performance.. It is also called Gelboflex.

Film torsion and flexing Gelbo endurance tester ASTM F392 Technical data

Principle

The sample (200*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.
