About De-Mattia Flex Tester
The ability of rubber products to withstand repeated flexing without developing cracks is of prime importance where such products are used in conditions undergoing repeated flexing.
Flexing endurance of rubber products is determined by simulating in the laboratory the action of flexing repeatedly under standard conditions of speed, mode, and degree of flexing.
One of the accepted procedures for determination of flexing resistance makes use of a De Mattia flexing tester. This tester provides useful information about the resistance of compounds of vulcanized rubber to flex cracking when subjected to flexing. Cracks develop in that part of the surface where stresses are set up during flexing, or if that part of the surface initially contains a crack, cause this crack to extend in a direction perpendicular to the stress.

FAQs of De-Mattia Flex Tester:
Q: How does the De-Mattia Flex Tester measure crack or flex resistance in rubber samples?
A: The De-Mattia Flex Tester measures crack or flex resistance by subjecting up to six mounted rubber specimens to repeated flexing movements. The presettable digital cycle counter records each flex cycle, allowing for precise determination of when cracks begin to appear, up to a maximum of 100,000 cycles.
Q: What specimen sizes and types are compatible with this tester?
A: The tester accommodates six specimens of approximately 70 mm in length by 45 mm in width. It is suitable for various rubber or vulcanized samples, complying with IS 3400 (Part 14) and ASTM D430 standards for dimension and test configuration.
Q: When should the emergency stop or overload protection features be used?
A: The emergency stop button should be pressed immediately in case of any operational malfunction or safety hazard during testing. The overload protection automatically engages to safeguard the machine and operator if excessive force or an unexpected mechanical load is detected.
Q: Where is the De-Mattia Flex Tester typically used?
A: This tester is widely used in rubber testing laboratories across manufacturing, quality control, research and development sectors, particularly in India by exporters, manufacturers, and suppliers needing reliable flex resistance analysis of their materials.
Q: What benefits does the digital cycle counter provide over manual counting methods?
A: The digital cycle counter ensures accurate, automatic recording of each flex cycle with 1 cycle accuracy and a 1 cycle resolution. This eliminates errors associated with manual counting, provides real-time response, and supports automatic machine stop when the preset cycle count is reached.
Q: How is the De-Mattia Flex Tester operated and specimens mounted?
A: The device is controlled manually through a push-button interface. Adjustable clamps are provided for easy and secure mounting of each specimen, and a sample cutting template is included to ensure conformity in specimen preparation. The user manual outlines step-by-step setup and procedure.
Q: What are the main advantages of using a powder-coated mild steel frame for this tester?
A: A powder-coated mild steel frame offers enhanced corrosion resistance, mechanical strength, and long-lasting durability. This construction ensures the device maintains stable performance and extends its operational lifespan in laboratory environments.
