Gelbo Flex Durability Tester for Flexible Barrier Materials and complies with ASTM test method F392

The Gelbo Flex Durability Tester is a precision instrument designed to evaluate the flex durability of flexible barrier materials. Compliant with ASTM F392 standards, this tester simulates real-world conditions to assess how materials withstand repetitive twisting and compression. Industries such as packaging, food, pharmaceuticals, and academia rely on this tester to ensure material integrity during handling, transportation, and storage.

Key Features

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

• PLC Control with 7-Inch Touchscreen: Offers intuitive operation and real-time monitoring of test parameters.

• Multiple Test Modes: Includes five standard test conditions (A-E) to simulate various stress scenarios.

• Four Test Stations: Allows simultaneous testing of multiple samples, increasing efficiency.

• Adjustable Flex Angles and Strokes: Flex angles of 440° (90 mm) and 400° (80 mm) with horizontal strokes of 155 mm or 80 mm.

• Sample Size Compatibility: Accommodates samples measuring 280 mm x 200 mm.

• Optional Micro Printer: Facilitates immediate printing of test results for documentation.

Technical Specifications

Applications

The Gelbo Flex Durability Tester is essential for industries requiring rigorous testing of flexible materials:

• Packaging Industry: Evaluates the durability of films and composites used in packaging to prevent failures during distribution.

• Food and Beverage Sector: Ensures barrier materials maintain integrity to protect contents from contamination.

• Pharmaceutical Industry: Tests the robustness of packaging materials to safeguard medicinal products.

• Academic and Research Institutions: Provides a reliable method for studying material properties under stress.

Testing Principle

The tester operates by securing a sample between mandrels and subjecting it to a combination of twisting and horizontal motions. This simulates the mechanical stresses materials encounter in real-life scenarios. The standard testing conditions are:

• Condition A: Full flex for 1 hour (2,700 cycles)

• Condition B: Full flex for 20 minutes (900 cycles)

• Condition C: Full flex for 6 minutes (270 cycles)

• Condition D: Full flex for 20 cycles

• Condition E: Partial flex for 20 cycles

Post-testing, samples are examined for pinholes or delamination, indicating material failure.

Compliance and Standards

• ASTM F392: Standard Test Method for Flex Durability of Flexible Barrier Materials.

Advantages

• Enhanced Product Safety: Identifies potential weaknesses in materials, preventing product failures.

• Cost Efficiency: Reduces material waste by ensuring only durable materials are used.

• Quality Assurance: Provides data-driven insights to maintain high-quality standards.

• Versatility: Suitable for a wide range of materials including films, composites, and coated papers.
