LT-XZ30-12 Leather Flex Tester

Short Description:

This Leather Flex Tester evaluates the flex resistance of dry or wet leather and leather coatings, suitable for various types of leather with a thickness of less than 3.0 mm. The upper test surface is folded inward and clamped in a moving fixture, while the lower test surface is folded outward and secured in a stationary fixture. The movement of the upper fixture repeatedly flexes the specimen, allowing for inspection of any resulting cracks, finish damage, or other defects to determine durability under repeated bending stress.
