Leather Shrinkage Temperature Tester A specialized instrument designed to determine the shrinkage temperature of leather materials—a critical indicator of leather quality, processing stability, and heat resistance. This tester measures the temperature at which leather begins to shrink under controlled heating, helping assess the integrity of collagen fibers (a key component in leather) and the effectiveness of tanning processes.
Operating by gradually heating a leather sample in water or glycerin while monitoring dimensional changes, the machine precisely records the shrinkage onset temperature and the maximum shrinkage percentage. This data is vital for evaluating:
Tanning efficiency (e.g., chrome-tanned vs. vegetable-tanned leather)
Heat resistance for leather used in high-temperature applications (e.g., automotive upholstery, industrial gloves)
Quality consistency across leather batches
Compliance with industry standards for durability and performance
Compliant with international standards such as ISO 3380, ASTM D6076, and IULTCS IUP 18, this tester is essential for tanneries, leather goods manufacturers, automotive suppliers, and quality control labs. It ensures that leather materials meet specifications for heat stability, reducing product failures in end-use scenarios where heat exposure is common.
