Overview:
Flex Crack Resistance Testing evaluates the ability of leather to resist cracking or surface damage when subjected to repeated flexing. This test is critical for determining the durability and lifespan of leather used in applications such as footwear, upholstery, automotive interiors, and apparel.

Test Description:
Pre-conditioned leather samples are mounted on a Bally Flexing Tester, which bends the material repeatedly at a fixed angle and frequency. After a specified number of cycles, the samples are visually inspected for signs of cracks, crazing, or delamination.

Purpose & Benefits:

• Determine flex fatigue resistance of leather under stress
• Predict product lifespan and performance in dynamic applications
• Essential for materials used in footwear uppers, gloves, belts, and automotive interiors
• Support R&D, quality assurance, and compliance testing
