Flex Durability Tester

Welcome to Cell Instruments, where we specialize in providing top-notch testing instruments designed to elevate the quality standards of materials across various industries. Flex Durability Tester, a crucial tool for measuring resistance against repetitive strain in films, composites, and coating films.

Application

The flex durability 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 Gelboflex. Good flex crack resistance will reduce the propensity of the package developing holes during the distribution cycle thereby destroying the package integrity.

Sampling and motion

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.

Additionally, our Flex Durability Tester offers five pre-programmed test conditions to cater to diverse needs:

• Mode A– Full flex for 1 hour (2,700 cycles),
• Mode B– Full flex for 20 minutes (900 cycles),
• Mode C– Full flex for 6 minutes (270 cycles),
• Mode D– Full flex for 20 cycles,
• Mode E– Partial flex for 20 cycles.
