Gelbo Flex Durability Tester ASTM F392 Flex Failure Tester Plastic film testing machine

The Gelbo Flex Durability Tester is a specialized instrument designed to evaluate the flex resistance of flexible barrier materials, including plastic films, composites, and coated papers. By simulating repetitive twisting and compression motions, it assesses the material's ability to withstand mechanical stresses that can lead to pinhole formation and compromised barrier integrity.​

Key Features:

• Compliance with ASTM F392: Ensures standardized testing procedures for reliable and reproducible results.​

• Multiple Test Conditions: Supports Conditions A through E, allowing for varied testing scenarios to match real-world applications.​

• User-Friendly Interface: Equipped with a PLC control system and a 7-inch HMI touchscreen for intuitive operation.​

• High Throughput: Features multiple test stations (typically 3 or 4) to facilitate simultaneous testing of samples.​

• Adjustable Parameters: Offers flexibility in setting flex angles (440° or 400°) and stroke lengths (155 mm or 80 mm) to accommodate different material types and testing requirements.​

• Robust Construction: Built with stainless steel and anodized aluminum for durability and longevity in laboratory environments.

• Safety Features: Includes safety interlocks, guards, and emergency stop functions to ensure operator safety during testing.
